How to Speed up Safari on Your Mac

In this article you will find the following:

Safari is the fastest browser on the Mac, but it isn't immune from slowdowns and performance issues. If web pages take longer to load or site navigation doesn't feel responsive, read on to learn how to speed up Safari on Mac.

  • How to speed up Safari on Mac

Is Safari running slow on your MacBook, iMac, or Mac mini? Connectivity issues, unoptimized extensions, cache corruption, and a host of other reasons often cause that. Try the suggestions in our guide to get Safari running smoothly on Mac again.

Before you start   If you want to speed up Safari on Mac quickly, download MacKeeper . It's an Apple-notarized maintenance utility that helps prevent browser slowdowns and other Mac-related issues.     MacKeeper lets you free up the RAM, delete unwanted Safari extensions, get rid of junk files, and more with considerably less hassle than manual maintenance. You get one fix for free, so don't hesitate to check if it works for you.

Check if your internet's slow

If webpages in Safari take too long to load or fail, it's a good idea to begin by figuring out if it's just a matter of your internet being slow. The best way to do that is to use an online speed checker like or .

Restart your router if you find that your internet isn't uploading or downloading at a decent rate. If that doesn't speed it up, learn what else you can do to fix a slow internet connection on Mac .

Also, don't discount server-side issues. If the problem is limited to a specific site, use a website monitoring tool such as Downdetector to determine if you're dealing with a server outage.

  • Close unnecessary tabs in Safari

Although Safari is adept at handling dozens of tabs, having too many open simultaneously will eventually take its toll on your Mac's memory. That creates delays while loading new pages, and the performance hit could also result in erratic browser behavior.

The quickest way to speed up Safari on Mac is to shut down unnecessary tabs as soon as you notice any slowdowns. Getting used to moving between and closing tabs using the Ctrl + Tab and Command + W keyboard shortcuts can make the process even faster.

  • Shut down apps and resource-intensive processes

Tabs aside, Safari will run slowly on the Mac if you have too many applications open. Check your Mac's Dock and quit anything you aren't actively using. Try force-quitting troublesome programs if you can't close them normally.

On the other hand, various apps and related processes can spin out of control and consume too much processing power and memory. Use the Activity Monitor to locate and stop them.

  • Open the Launchpad and select Other > Activity Monitor
  • Sort your Mac's activity using the % CPU column and shut down any third-party processes that use a significant amount of CPU
  • Switch to the Memory tab and stop third-party items that use lots of RAM.

If you always end up pushing the hardware on your Mac to its limits, consider using MacKeeper's Memory Cleaner feature to keep things under control.

  • Disable unnecessary Safari extensions

Running Safari with multiple extensions increases the load on the CPU and RAM. That translates to slower browser performance, so review your list of browser add-ons and disable any items you don't regularly use.

  • Open Safari and select Safari > Preferences on the menu bar
  • Switch to the Extensions tab
  • Clear the boxes next to any extensions you want to disable.

Our team highly recommends you update Safari extensions periodically via the Mac's App Store to ensure they run in top shape. If you notice anything suspicious, learn how to remove malicious browser extensions and toolbars from your Mac.

  • Switch DNS servers for Wi-Fi and Ethernet

DNS (short for Domain Name System) is a cataloging system that matches domain names with IP addresses. Not all DNS providers are fast, so changing your Wi-Fi or Ethernet's DNS settings to a popular service like Google DNS can speed up Safari on Mac. For best results, clear the DNS cache on your Mac before you begin .

  • Open the Apple menu and select System Preferences
  • Select the Network category
  • Select Wi-Fi/Ethernet > Advanced
  • Switch to the DNS tab
  • Select OK > Apply to save your changes.
  • Clear the Safari cache and cookies

Like most web browsers, Safari caches various forms of site data — images, HTML files, and JavaScript code — to improve load times in subsequent visits. However, a bloated or corrupt cache can adversely impact performance and result in Safari running slow on the Mac. You can clear the Safari cache after activating its hidden Develop menu .

  • Switch to the Advanced tab and check the box next to Show Develop menu in menu bar
  • Select Develop on the menu bar and pick the Empty Caches option.

Corrupt, outdated, or privacy-invasive browser cookies can also slow down Safari. If deleting the Safari cache didn't make much difference, try deleting its cookies next.

  • Select Safari > Clear History on the menu bar
  • Set Clear to All history
  • Select Clear .

Update the Safari browser

Safari receives occasional bug fixes and performance enhancements from Apple, and these arrive alongside regular macOS updates .  

To update your Mac:

  • Select Software Update
  • Wait until the Software Update tool checks for newer macOS updates and select Update Now to install any pending updates.

To have your Safari browser updated, you need to update macOS to the latest version by going to Software Update from the System Preferences menu.

Even if a new macOS update doesn't include anything Safari-related, installing it will still improve general performance across native apps. Make it a point to install macOS updates as soon as possible.

  • Reset Safari to factory defaults

Corrupt browser preferences and other underlying issues can also play a factor, so sometimes, the only way to fix a slow instance of Safari on Mac is to reset it to factory defaults.

A Safari reset deactivates all extensions and reverts each browser setting to its defaults, allowing you to start over with a clean slate. You will not lose your bookmarks or passwords during the process.

  • Save your work and exit Safari
  • Open Finder, select Go > Go to Folder on the menu bar, and visit the ~/Library/Preferences/ directory
  • Search for file and delete it
  • Reopen the Go to Folder box and visit ~/Library/Safari/ . Then, delete each item within the folder except the Bookmarks.plist file
  • Visit ~/Library/Containers/ , search for Safari, and delete all files and folders that appear among the search results
  • Open Safari and visit its Preferences pane to reactivate any essential extensions. Also, move between tabs and modify your browser settings the way you want.
  • Boot your Mac into Safe Mode

If none of the fixes above help speed up Safari, try booting your Mac into and out of Safe Mode. That helps flush out various forms of temporary data that can interfere with Apple's browser.

On an Intel Mac, you can get to Safe Mode while holding down the Shift key during the reboot phase. However, if you use an Apple Silicon Mac, you should:

  • Shut down your Mac
  • Turn it on but keep holding the Power button until you get to the Startup Options screen
  • Hold the Shift key and select Macintosh HD > Safe Mode .

To start M1-based Mac in Safe Mode, restart your Mac and hold the Shift key until you see the Startup Options screen.

In Safe Mode, repeat the fixes above if you could not complete them earlier. Then, restart your Mac normally. To delete additional forms of temporary data that can slow down Safari, learn how to delete your Mac's application and system caches .

  • Full steam ahead

Keeping Safari in top shape is crucial for a great web browsing experience. Avoiding too many open tabs, shutting down unwanted apps and processes, and cutting down on the number of active extensions can go a long way toward making that happen. Occasionally clearing the Safari cache and keeping your Mac up-to-date will significantly minimize browser slowdowns and other issues. If manual Mac maintenance feels like a drag, don't forget to download MacKeeper .

  • If resetting doesn’t help, try moving closer to the router or removing any obstacles interfering with the signal.
  • If the above steps don’t improve your internet speed, it might be time to contact your Internet Service Provider (ISP) for further assistance.

2. Force Close and Relaunch Safari

At times, Safari or any of its tabs might encounter errors or issues that consume excessive system resources, leading to slowdowns. Force closing and re-launching Safari can terminate these problematic processes and give the browser a fresh start.

Here’s how to force quit Safari and relaunch it on your Mac:

  • Click the Apple logo in the top-left corner of your screen and select Force Quit from the drop-down menu.

click the apple icon and select force quit

  • In the new window, select Safari and click the Force Quit button.

3. Close Unwanted Tabs

Each open tab in Safari consumes your Mac’s memory and processing power. Having multiple tabs open, especially those with heavy content or active scripts, can significantly slow down the browser and even the entire system.

Closing unnecessary tabs can free up valuable resources and enhance Safari’s performance. Here’s how to go about it:

  • Take a look at all the tabs you have open in Safari. Identify which ones are not currently needed or are consuming significant resources.
  • Click the small x icon on the left of each tab you wish to close.

  • After updating Safari, navigate different websites and assess whether the browser’s performance has improved.

10. Disable DNS Prefetching

DNS prefetching is a feature that pre-resolves domain names before you click a link, aiming to improve page load times. However, this feature can cause Safari to slow down or become unresponsive on some networks. Disabling it can help alleviate these issues.

Here’s how you can disable DNS prefetching:

  • Navigate to Finder > Applications > Utilities > Terminal to open the Terminal application on your Mac.

launch terminal from utilities

  • Click the OK button in the DNS Servers window to save the changes.

click the ok button to save the changes

  • After switching the DNS provider, open Safari and browse through different websites to check if there’s an improvement in speed and responsiveness.

12. Kill Resource-intensive Processes

Some processes running on your Mac can consume a significant amount of system resources, affecting the overall performance of your computer and, consequently, Safari. Identifying and terminating these resource-intensive processes can free up system resources and improve Safari’s responsiveness.

Here’s how you can kill resource-intensive processes on your Mac :

  • Open Activity Monitor by going to Finder > Applications > Utilities > Activity Monitor .

open activity monitor in utilities

  • In Activity Monitor, you’ll see a list of active processes sorted by their usage of system resources such as CPU, Memory, Energy, Disk, Network, or Cache .

Apple’s Safari is known to be amongst the best browsers due to its fast performance and simple interface. However, it can still run into performance issues that can be frustrating. There could be a multitude of reasons for Safari running slower than usual. So, we tried a few simple methods that might be able to fix the issue and get back on track.

Some possible reasons for this issue are the build-up of cache or cookies, outdated browsers, extensions, or plug-ins that are not being used. Once you are able to identify the issue, you can simply follow the steps to remove cache and extensions or even update the browser.

Well, let us look at everything we need to know in detail and figure out all the methods that might work best for you.

Why Is Safari So Slow?

1. build-up cache and cookies, 2. software update, 3. extensions and plug-ins issue, 4. large number of open tabs, 5. network issues, 6. limited storage space, 7. contact apple support, frequently asked questions.

Your Safari browser is running slow because of the build-up of cache and cookies. Or it could even be because you are using an outdated version of the browser, and it needs an immediate update. Furthermore, this could be simply because too many tabs are open on the system, and thus it is eventually slowing down the entire software.

As we said, this could be because of any underlying cause. You can fix all of it by simply restarting the system or the browser itself. Or you might need to try other methods that can take a few more steps. Here are some fixes you can try that worked for us too.

7 Reasons Why Safari is Running Slow + Fixes

We all know the basic idea behind using cache and cookies. They are used by websites or the system to speed up your browsing experience. However, the more you are active on the internet, the more these files are piled up over time.

Hence, there isn’t enough space for the browser or the system to store any more of these small files. So, we need to eliminate these to fix your Safari issues. Here is how you can do it.

  • Open Safari Browser.
  • Now, click on History on the top taskbar and choose Clear History in the drop-down menu.

Build-Up Cache and Cookies

  • Select the time duration besides the Clear option, then click on Clear History.

Clear History

The above steps will clear the history and the cookies from the site. Now close Safari and start again to check if the issue is fixed.

Here is another way you can empty caches on the Safari browser.

  • Open the Safari browser and click on Develop on the top taskbar.

Safari browser

  • Now, from the drop-down menu option, select Empty Caches or press Option + Command + E.

Empty Caches

Another method you can try is updating the Safari browser by updating your macOS . Since Safari is an in-built software developed by the tech giant itself, they often release updates to fix such errors.

Here is how you can check for updates and update your Safari app when needed.

  • Go to the Apple menu and then choose System Settings .
  • Then click on Software Update.
  • Wait a few seconds for the system to check for an available update. Install the update if available.

Software Update

Once you update your macOS, your Safari app will also be updated. You can then wait for the system to restart and check if the app works fine.

Some extensions or plug-ins might be outdated and cause your Safari to slow down and cause performance issues. Hence, you can update or uninstall these extensions from your system.

You can follow the steps below to check which extensions you are currently using and then uninstall the ones you are not using anymore.

  • Open Safari browser.
  • Go to the Safari option on the taskbar and choose Settings.

Extensions and Plug-ins Issue

  • Now, click on the Extensions option on the menu bar.
  • Next, choose the Extension you want to remove and select Uninstall.

Unistall Extension

You can keep doing this for all the extensions you do not want to keep and uninstall them from your browser. This will eventually speed up the performance of Safari.

Have you been currently using too many tabs on your Safari browser? Well, this could be one of the biggest reasons your Safari browser has slowed down or even glitched overall. The best way to go from here is simply close some tabs and give your browser a breather.

If that does not work, you might have to close the browser and restart the system. For this, simply right-click the Safari icon in the dock below. Press Quit and the browser will close with all its tabs.

Before trying out any other solution, it is best to check your internet connection and ensure it works properly. Your network issues might be causing the website and other downloads to slow down. 

Ensure your router is properly connected or your MacBook receives a proper internet connection. For this, you can check your internet speed through multiple sites on the web. If everything looks fine, you can try the other methods listed below.

You might need to clear some storage space on your Mac . Some apps fail to function because your system does not have enough space to run the in-built apps such as Safari.

For this, you can check the current status of your storage on Mac and determine how you can make space for the system apps to run smoothly.

  • Go to the Apple menu and choose System Settings .
  • Scroll down to open General and then choose Storage.

Limited Storage Space

Here, you can check all the sections that have taken up the maximum space and then delete some of the files.

The last resort here is to contact Apple support for some guidance. Although you can also check for some hardware issues, it is best to speak to an executive from Apple support.

Simply visit the official Apple website and connect to an online executive where you can present your issues and try their suggested fixes.

You can start by updating the macOS, which will, in turn, update the Safari app as well. Moreever, you can also clear caches and cookies to help bring the safari to speed.

Safari is known to be faster on Apple devices such as your MacBook. At the same time, Google Chrome performs the best on all devices, including your smartphones. However, it depends largely on the operating system and the device’s hardware.

The fastest browser for Apple is indeed Safari. It is built for macOS and iOS devices, providing an optimized browsing experience.

The fixes to a slow-running Safari are simple. Clearing your cache, updating the app or your macOS, closing unwanted tabs, and clearing storage space are all excellent ways of ensuring your Apple search engine runs perfectly. 

If these do not work, you can check your internet connection and close the tabs you are working on. The more tabs you have opened, the slower it will work. Similarly, there are other methods too that are tried and tested to fix Safari issues, and you can try them as well before contacting Apple Support.

Why Is Safari So Slow? 10 Reasons Your Browser Is Sluggish (and How to Fix It)

As the default browser on Mac, Safari offers a fast, efficient, and privacy-focused browsing experience – at least in theory. In reality, many Mac users find Safari slow, unresponsive, and frustrating to use. If you‘re wondering "why is my Safari so slow?" and how to speed it up, you‘ve come to the right place.

In this guide, we‘ll break down the top 10 reasons your Safari browser might be running slowly on your Mac, explain the technical details behind why they cause slowdowns, and walk you through step-by-step solutions to get Safari running like new again.

We‘ll cover everything from simple fixes like closing tabs to more advanced troubleshooting like clearing caches, tweaking hidden settings, and testing in Safe Mode. Whether Safari started slowing down out of the blue or it‘s been sluggish for a while, you‘ll find a solution here.

But first, let‘s look at some key statistics around Safari browser performance and usage:

  • Safari is the 2nd most popular desktop browser behind Google Chrome, with a 9.84% market share as of September 2021 (source: StatCounter )
  • The average number of tabs and windows users have open in Safari at once is 10-20 (source: AppleInsider )
  • Safari uses around 10-50% CPU on average when browsing (source: OSXDaily )
  • Safari‘s JavaScript performance lags behind other browsers in benchmark tests (source: Computerworld )

Now that we have some context around Safari‘s performance and market share, let‘s dive into the top reasons it can slow down and what you can do about it.

1. Too Many Tabs and Windows Open

One of the most common reasons for Safari feeling slow and sluggish is simply having too many tabs and windows open simultaneously. Each open tab consumes system resources, especially processing power (CPU) and memory (RAM).

The more tabs and windows you have open, the harder your Mac has to work to juggle them all, leaving fewer resources available for tasks within Safari and other apps. Add in video/audio content and animated scripts on web pages, and resource demand jumps even more.

Look at Activity Monitor (in Applications > Utilities) with Safari running to see how much CPU and memory it‘s using. Sorting processes by %CPU and Memory will show you which tabs/sites are hogging resources.

Safari CPU and memory usage in Activity Monitor on Mac

To lighten the load on your Mac and speed up Safari, close any tabs and windows you‘re not actively using. A quick way to close multiple tabs:

  • Hold down Command and click each tab you want to close.
  • Without releasing Command, press W to close the selected tabs.

Alternatively, press Command-Option-W to close all tabs in the current window except the active one.

If you don‘t want to lose your tabs, Safari 13 and later offers a Start Page with Favorites and Frequently Visited sections for quickly re-opening closed tabs later on. Safari also has a Tab Overview button that shows thumbnails of all open tabs to help you find and manage them.

2. Problematic Safari Extensions

Extensions are a double-edged sword in Safari – while they can add useful functionality, they can also badly hurt performance and security if poorly coded or malicious.

According to Apple, the average Safari user has 1-5 extensions installed. But some extensions, especially ad/content blockers and download managers, are notorious resource hogs that can single-handedly bring Safari to a crawl.

Safari extension issues include:

  • Buggy, poorly optimized code
  • Malware masquerading as legitimate extensions
  • Heavy CPU and memory usage
  • Excess network activity and tracking
  • Modifying page content in a performance-intensive way

To see if a problematic extension is slowing down Safari, open the Extension Manager in Safari settings and disable all extensions. Then re-enable them one by one, relaunching Safari each time to gauge performance impact.

Managing and disabling Safari extensions

Be extremely judicious about which extensions you keep enabled and consider axing any that aren‘t absolutely essential. Sticking to vetted extensions from the official Safari Extensions repository is safest.

As security researcher Patrick Wardle notes:

"Safari extensions, just like any code that runs on your machine, have the potential to exfiltrate sensitive user data. Malicious extensions may attempt to access website data, or even record and exfiltrate your browsing history. As such, it‘s only prudent to limit one‘s attack surface, by only installing extensions from trusted sources."

3. Bloated Browser Cache and Website Data

As you browse the web in Safari, the browser cache collects site data like images, scripts, and cookies to speed up repeat visits. Too much accumulated cache data can eventually slow down Safari.

Safari may also hang when purging old cache files to make room for new ones if the database is oversized. The average Safari cache is around 200 MB in size, but can balloon to multiple gigabytes if never cleared.

Safari history, cookies, autofill, and other website data can have a similar effect when left unchecked. Safari‘s local storage system for websites can reach into the billions of database files under heavy usage.

Clearing out Safari‘s various data caches can reclaim the lost space and restore Safari‘s original performance:

  • In Safari settings, go to Privacy and click "Manage Website Data."
  • Select one or more websites and click "Remove" to delete their data, or "Remove All" to wipe everything.
  • Next, go to "Clear History" in the Safari menu and choose how far back to purge.
  • Finally, click the "Develop" menu and select "Empty Caches."

Managing and removing Safari website data and caches

After clearing caches and data, restart Safari. Note that removing website data will sign you out of sites, clear autofill entries, and reset website settings/permissions.

To prevent Safari‘s caches from getting bloated again, go to Safari prefs > General and uncheck the "Preload Top Hit in the background" option. This tells Safari not to preload pages before you browse to them.

4. Outdated Safari/macOS Version

Running an outdated version of Safari or macOS can cause serious performance issues, as updates often include bug fixes, security patches, and speed improvements.

Apple rolls out major new Safari versions annually with each new macOS release, with smaller updates throughout the year. According to Apple, 65-75% of users are on the latest macOS version at any given time. Newer macOS versions usually get updates sooner and more frequently.

macOS Big Sur adoption rate from Apple

To update Safari and macOS:

  • Open System Preferences > Software Update.
  • If updates are available, click Update Now.
  • Make sure "Automatically keep my Mac up to date" is checked.

If Safari is still slow after updating, try Apple‘s Safari Technology Preview. This is a beta version that includes the latest performance enhancements and Experimental Features:

  • Download Safari Technology Preview from Apple‘s developer site.
  • Install it while keeping the stable Safari release.
  • Test the Preview version to see if it resolves performance issues.

Download the Safari Technology Preview beta

5. Internet Connectivity Problems

Sometimes Safari only feels slow because of issues with your internet connection rather than the browser itself. Safari can‘t load pages faster than your internet speed allows.

According to, the average fixed broadband download speed in the US is 167 Mbps. The FCC defines "broadband" as 25 Mbps down and 3 up. So if your connection falls well below those benchmarks, you‘ll definitely feel it in Safari.

Average US internet speeds from

To test your connection:

  • Use or to measure upload/download speeds.
  • Compare to your normal/advertised speeds.
  • Check modem/router connection indicators.
  • Restart network hardware if needed.

If you suspect an ISP issue, contact your provider and have them run line tests. They may need to send a tech to diagnose problems with cabling, network devices, or the connection from the pole.

6. DNS Server Problems

Sometimes Safari issues arise from slow domain name resolution rather than the browser itself. Safari relies on DNS servers to translate the domain names you enter into IP addresses so it can load websites.

By default, your Mac gets its DNS servers from your router, which usually uses the ones provided by your ISP. ISP DNS servers are often slow and unreliable.

Switching to a fast, reputable 3rd-party DNS provider can speed up Safari noticeably. Cloudflare, Google, OpenDNS, and Quad9 all offer free DNS for public use. These improve both speed and security:

  • Cloudflare:,
  • Google:,
  • OpenDNS:,
  • Quad9:,

To change your DNS on macOS:

  • Go to System Prefs > Network.
  • Select WiFi/Ethernet in the left sidebar and click Advanced.
  • Go to the DNS tab and add the new DNS entries.

Configuring custom DNS servers on Mac

After updating DNS, empty your Safari caches for good measure. The new servers should feel snappier when loading sites.

7. Overall System Performance

Sometimes Safari only feels slow because your Mac as a whole is bogged down. Safari has to compete with other processes for finite system resources.

Open Activity Monitor and sort by %CPU and Memory to see what‘s eating up resources. Quit or Force Quit any unnecessary resource-heavy processes.

Top Mac processes by CPU usage

Also check your Mac‘s free disk space in Finder. At least 10% of the disk should remain free to leave room for caches and virtual memory. Low disk space will severely impact system performance.

Disk space usage on Mac

If your Mac is always low on memory, consider upgrading to a higher RAM capacity if your model allows it. More RAM means Safari can hold more in active memory without relying on the slower virtual memory system.

8. Safari‘s Performance vs. Other Mac Browsers

If none of the previous troubleshooting makes Safari feel faster, you might wonder how it compares to other Mac browsers like Chrome, Firefox, and Opera.

Sadly, Safari lags behind other browsers in performance benchmarks that measure JavaScript speed and web app responsiveness. Despite Apple making continuous improvements, Safari remains slower than Mac Chrome and Firefox in many tests.

Safari benchmarks vs. Chrome and Firefox on Mac

However, Safari beats most other browsers handily in memory efficiency and energy impact, which are important on laptops. It‘s not as big a RAM or battery hog.

Ultimately, whether Safari is "fast enough" comes down to your Mac‘s hardware, internet speed, and the websites you frequent. A stock install of Safari on a new M1 MacBook Pro will feel much faster than a bloated one on a 5+ year old MacBook Air.

If you like Safari‘s Mac integration and syncing but not its speed, consider:

  • Microsoft Edge (Safari‘s rendering engine with more features)
  • Firefox (similar speed to Safari but with stronger privacy)
  • Chrome (raw speed leader but heavyweight)
  • Opera (Chromium-based alternative with built-in VPN)

9. Experimental Safari Features

If you‘ve exhausted all other performance tweaks and still find Safari sluggish, you can try enabling some experimental features that may make it feel faster:

  • Prioritize specific websites in Settings > Advanced> Experimental Features. This gives more resources to whitelisted sites.
  • Turn on the "Disable Web Page Preview Tab Hover" flag in about:flags. This skips the slow animations when hovering over tabs.
  • Enable the "QUIC protocol" flag in about:flags. This uses a faster, more efficient protocol by default.

Enable experimental Safari features

Note that experimental features can have unintended side effects and should be tested carefully. They may also be removed or changed at any time.

10. Issues with Specific Websites

Lastly, sometimes performance problems are isolated to specific buggy or poorly coded websites rather than Safari as a whole. A site may have unoptimized scripts, tracking, or assets that disproportionately impact the browser.

To see if a particular site is causing Safari slowness:

  • Open the site in a private window to rule out extension interference.
  • View the Web Inspector (Develop > Show Web Inspector).
  • Click the Network tab and reload the page.
  • Look for script or resource files with long load times.

Using Safari's Web Inspector to find slow page resources

For consistently problematic sites, consider reaching out to the webmaster and kindly informing them of the issues to give them a chance to optimize.

As a last resort, you can use Safari‘s Advanced prefs to select "Never use font sizes smaller than [size]" to override a site‘s stylesheet and force more readable text.

As we‘ve seen, a wide variety of issues can contribute to Safari feeling slow on Mac, from tabs to extensions to connection problems. Hopefully with the guidance in this article, you‘ve managed to restore some speed.

The key things to check are the number of open tabs/windows, the extensions you have installed, the size of the caches, and your DNS/internet speed. Keep them all in check for the smoothest Safari experience.

If all else fails, consider an alternate Mac browser like Chrome or Firefox, at least for a while. Let us know what made the biggest difference for your Safari speed!

Experiencing Safari slowdowns on your Mac? Whether it’s loading issues or post-Monterey update sluggishness, these common glitches can be frustrating. In this guide, we’ll explore why Safari is lagging and provide solutions for a smoother browsing experience.

Note: if Safari is not just slow, but keeps freezing and crashing, read this post instead for more troubleshooting tips.

Key Takeaways:

  • Clear Cache: Overloaded cache can slow Safari. Clear history and cache through Safari settings for a speed boost.
  • Extensions Check: Outdated or excessive extensions can drag Safari down. Remove unnecessary ones via Safari settings.
  • Update Safari: An outdated Safari version might cause slowness. Update it through the App Store.
  • Network Check: Slow Safari might be due to network issues. Test internet speed to rule this out.
  • User Account Check: A corrupted user account or macOS issues can affect Safari. Test on a new user account and run disk utility checks.
  • Tab Management: Too many open tabs strain Safari. Close unnecessary tabs for better performance.

Why is Safari so Slow?

Safari could be slow because you’re using an outdated version of Safari. The cache might be overworked, or you might be facing network issues. Additionally, you might have too many tabs open that are causing the app to slow down.

Important Tips

It’s normal for safari to run slow on certain websites.

By certain websites, we mean “heavy” sites that are loaded with flash or video ads on the pages you browse. Worse yet, some even auto-play without you clicking on. They tend to have your MacBook heat up quick.

The best option is to close those pages immediately when you finish reading the content on it, or you could install AdBlock Plus (Safari compatible) to block the ads from displaying.

Stop excessively multitasking

You’d be surprised how much better 90% of programs work when you don’t try and use them at the same time as a dozen other apps. It seems like a simple solution, but it is often the best one.

Take care of Safari

Some methods are a matter of habit, such as regularly clearing your cache or making sure the app is up to date. Imagine your computer as a car that needs regular maintenance to run well.

Don’t neglect the computer

Macs are not immune to viruses, despite the common perception. They also aren’t immune to file corruption or errors. Make sure you haven’t picked up anything unwanted while browsing that could be affecting Safari’s performance.

Slow Safari : 8 Possible Causes & Fixes

1. overworked cache.

The cache is a location on your Mac’s hard drive where Safari temporarily stores data that you use frequently. The cache allows Safari to reference this information quickly and therefore execute actions such as loading a specific page more quickly.

However, if the cache becomes full then Safari cannot add newer, more relevant material and is forced to use slower methods to respond to your demands.

Here’s how to erase the data in the cache so that Safari can work smarter rather than harder:

Start by erasing your history from Safari by navigating the menu bar along the top and choosing History > Clear History and Website Data .

 Clear History and Website Data

Once you click this, you’ll be shown a small pop-up window. Choose “All History” from the bottom of the drop-down, and then Clear History .

 Clear History

The next thing you can do is clear the cache using a more advanced method. First, go to the Safari menu and open Preferences.

Open Preferences

On the preferences panel, choose “Advanced” and then look for the checkbox at the bottom of the page that says “Show Develop Menu in Menu Bar”. Make sure this box is checked, then close Preferences.

Show Develop Menu in Menu Bar

You’ll notice a new tab has been added to your menu bar, called “Develop”. Click on this, and then choose “Empty Caches” from the list. You won’t be given any confirmation, but it will clear the cache and you can restart Safari and see if this has solved your problem.

Empty Cache

2. Bad Extensions

Most people are aware that Apple doesn’t play well with Flash, but this isn’t the only plugin that could be causing Safari to lag. Any extension or plugin that is outdated or not correctly optimized could be the “culprit”, and you should disable or remove as many as possible.

The easiest way to do this is to use CleanMyMac X , go to Extensions > Safari Extensions (the screenshot below), here you just select these unwanted plugins, and click the “Remove” button at the bottom to clean them all at once.

 Safari Extensions

Of course, you can also get this done manually, though the process will be a bit time-consuming if you have a list of extensions to disable or remove.

First, start by opening Safari, and then navigate to Safari > Preferences.

why is safari browser slow

In the preferences menu, choose the Extensions icon. You’ll be shown a list of all your extensions.


If you don’t use an extension, you should uninstall it with the button on the right side. If you use it but infrequently, simply uncheck the “enable” box. This should significantly speed up Safari, especially if you have been running a lot of extensions in the background.

3: Outdated Version of Safari

Because Apple makes Safari, it usually receives updates when macOS has a new version released or when there is a necessary patch. If you’re running an old version of Safari, this could be part (or even all) of your problem.

If you aren’t on macOS Big Sur or higher, your Safari is definitely in need of an update. To check what you’re running, go to the Apple Menu in the top left corner and choose “About this Mac”.

If you’re on an older version, your window will look something like this, displaying the version of macOS you’re running:

 displaying the version of macOS

If you’re already on macOS BigSur, it will look like this instead:

bigsur system preference

If you aren’t on the latest macOS yet, open the App Store from Finder, and navigate to updates. There will be at least one software update available, which you can expand. This will show you the update for Safari, which you can update separately or with any other updates you may have available.

Safari Version

4: Your Network

You might argue that the problems inside Safari are simpler to deal with, but sometimes it’s surprising that Safari isn’t necessarily the “culprit”. Your network can have a significant impact on Safari’s performance.

To find out whether your Mac has network issues, check out our other post to learn more.

To test the Internet speed, you can also use Google Fiber .

  • First, open the link on your Safari browser, then press the blue “play” button, and watch as your internet speed is tested.
  • The site will first test your upload and then your download speed.
  • Once you have your results, you can compare them with this link , which contains charts detailing what you should expect based on the connection type.
  • If your results are below expected, it might be time to contact your Internet Service Provider (ISP), especially if speeds fall far below what you’re paying for.

Note: if speed seems normal and falls in the expected ranges, then this probably isn’t your problem, and you should try some of our other solutions.

5: Your User Account or Mac Drive

Sometimes the issue runs a bit deeper than just a full cache. You could have a corrupted user account or your macOS version isn’t operating correctly. To determine if this is your problem, start by creating a second user account on your MacBook.

On the new user account, open Safari and try using it as you normally would. If Safari suddenly runs faster, it’s time to repair your normal user account.

Use spotlight (top right corner of the screen) to search “Disk Utility” and open it.

Disk Utility

Inside Disk Utility, select your account’s disk and make sure you’re on the “First Aid” tab. Then select “Repair Disk” from the bottom right corner (if this is unavailable, choose “Verify Disk” first).

Note: If your MacBook Pro is with macOS 10.10 Yosemite or earlier, you have two buttons to click on like below.

Repair Disk

However, if your MacBook Pro is with 10.11 El Capitan or later (you probably are), just click “First Aid” and run it to check and fix any issues it may find.

Running First Aid

The Disk Utility will repair any problems with your account. If it isn’t capable of fixing the problem, resetting your MacBook Pro is always an alternative if a bit tedious to do.

6: Close all extra tabs

The more tabs you have open on Safari, the slower your computer can run. If you don’t know what a tab is – it’s an open window. Even if you are only looking at a single tab at a time, the other open ones are using up the CPU, which puts a demand on your computer.

Newer MacBooks are capable of keeping multiple tabs open with relative ease. But if you have 10 or 20 or even more open simultaneously, you can run into performance issues that can slow down Safari significantly.

If you are experiencing slow performance, close any tabs you aren’t currently using, and you can see an increase in operating speed. 

7: Disable search suggestions

This is another quick fix that can often speed up Safari. Not many people know this one, so write it down or take a screenshot for future use.

To turn off search suggestions, complete the following steps: 

  • Click on Safari from the top of the window
  • Select Preferences
  • Select Search
  • In the Search settings window that appears, uncheck the box that says Include search engine suggestions

 turn off search suggestions

This can increase Safari speeds ever so slightly and help you see improved performance. 

8: Disable DNS prefetching

If you are running Safari version 5.0.1 or later, DNS prefetching might be slowing down your MacBook. This feature allows you to load a link on a page before you click on them, leading to faster browsing. But it can also slow down your computer with multiple pages trying to load and some website-related issues.

To disable DNS prefetching, follow these steps: 

  • Open the Terminal 
  • Enter this text: defaults write WebKitDNSPrefetchingEnabled -boolean false
  • Quit Safari
  • Reopen Safari

DNS prefetching will now be disabled for another small boost to the speed of your MacBook

‘All of these behaviors are typical symptoms related to Apple’s signature Internet browser. While Safari is a light-weighted browser optimized for use on all Mac machines, issues like above might force you to resort to third-party browsers (perhaps Chrome, stay away from Firefox) that tend to be faster.”

Chrome is developed by Google. When you use Chrome, not just your searches but EVERYTHING YOU TYPE and EVERYWHERE YOU GO is sent to and tracked by Google.

Don’t be a sheep. Don’t use Chrome.

10 Fixes When Safari Running Slow on Your Mac

How to fix this annoying problem

Author avatar

Apple touts Safari as the fastest browser out there, which may be true on iOS, but I regularly use Chrome on my Mac because Safari is just too slow. Sometimes a webpage won’t load or I won’t be able to navigate back and forth between pages or I can’t scroll without lagging.

It’s extremely frustrating considering Safari comes included with OS X and you expect it to just work. When it does, it’s a great browser, but when it doesn’t, you literally have to switch to a new browser.

Method 1 – Cache, History, Extensions

If you’re a heavy web user and you don’t have a lot of space left on your Mac, it might be worth emptying the cache, disabling extensions, and clearing up the history to ease the load on Safari. In order to do this, you first have to go to Safari and then Preferences .

safari preferences

Click on the Advanced tab and then check the Show Develop menu in menu bar box at the bottom of the dialog.


Exit the Preferences dialog and click on Develop in the Safari menu. Go ahead and click on Empty Caches . Once the cache is empty, click again on Develop and choose Disable Extensions .

empty caches

Finally, click on Safari and instead of Preferences like we chose above, click on Clear History .

clear all history

In the drop-down box, make sure to choose all history and then click the Clear History button.

Method 2 – Manually Clear Cache.DB File

The above steps should clear the cache in Safari, but if something is not working properly, it may not do so properly. In this case, you can manually do it. Open Finder, then click on Go and Go To Folder at the bottom.

go to folder

Now copy and paste the following path into the text box and click Go .

safari cache

Finally, right-click on the Cache.db  file and choose Move to Trash . Make sure Safari is closed when you are doing this step.

move to trash

Method 3 – Install Latest OS X Version

I’ve noticed that quite a few people who purchase Macs simply do not update their systems to the latest version of OS X. Even though we are on El Capitan right now, I have friends running on Mountain Lion, Mavericks, Yosemite, and even Snow Leopard!

If you don’t update OS X, you won’t get the latest version of Safari either. This means you could be stuck several versions behind and will be missing out on all the improvements and optimizations of the newest version.

The simplest way to upgrade is to go to the App Store and click on the link for the latest version of OS X, which is usually on the right-hand side.

os x el capitan

Method 4 – Turn Dashboard Off

If you’re still using an older Mac (2010 or earlier), you might have a graphics card issue. You can try something simple to see if it helps in Safari. I’m talking about disabling the Dashboard feature in Mission Control.

To do this, open System Preferences and then click on Mission Control. In the drop-down next to Dashboard , select Off .

turn dashboard off

This is not some surefire fix, but it has worked for some people, including myself. I have a Mid-2009 MacBook Pro and the dashboard was definitely slowing things down.

Method 5 – Change Search Settings

Another thing you can try is to change the search settings in Safari. Open Preferences  in Safari and then click on the Search tab.

safari search options

Try changing the search engine to Bing, restarting Safari, and see if there is any difference in the speed. Change it back to Google and then check again. You can also try unchecking all the options like search engine suggestions, Safari suggestions, a quick website search, preload top hit, etc. to see if that makes a difference.

Sometimes on a very slow Internet connection, all of these extra features may cause Safari to be even slower.

Method 6 – Change Network Service Order

If you have a machine that is connected to both WiFi and Ethernet, your issue could be caused by being connected to the network in two different ways. To see your connections, go to System Preferences and then click on Network .

You could try disconnecting one network source and seeing if that makes a difference or not. Switch to only the other one and test too. If you want to keep both connected, read on.

connected networks

By default, one connection will get priority over the other. As you can see above, my WiFi connection was getting higher priority than the Ethernet connection. You can change this by clicking on the little settings icon (gear) at the bottom of the list box.

set service order

Click on Set Service Order and another popup will appear where you can reorder the connections by dragging and dropping.

change service order

I moved Ethernet to the top and then clicked OK. After that, make sure you click Apply to on the System Preferences dialog.

Method 7 – Delete Preferences File

This probably won’t make much of a difference, but it’s worth a shot. Go to Finder , click on Go and then Go to Folder .  Type in the following path:

Scroll down the list till you see and delete that file.

safari plist delete

Method 8 – Use Different DNS Settings

Sometimes it may not be Safari causing the issue, but your DNS settings. By default, you’ll be using the DNS provided by your ISP, which is fine most of the time. However, using a public DNS might result in faster browsing.

google public dns

My favorite is Google Public DNS, which I use on all my computers. Check out my article on the best public DNS servers you can use for free.  To change the DNS server for your connection on OS X, you need to open System Preferences , click on Network , select the connection and then click on Advanced .

dns servers

Go ahead and click on the little + icon and then type in the IP addresses of the new DNS servers. Using Google has sped up my browsing not only in Safari, but also in other browsers.

Method 9 – Log Into Another Account

Sometimes the problem is with the user account you are currently using. It’s worth creating another user account (takes 1 min), logging into that account, and then running Safari. If it’s suddenly faster, then there is a problem with your user account. You can try to fix the problem by using Disk Utility. You can go to Spotlight and type in Disk Utility to open the dialog quickly.


Click on your hard drive in the left-hand pane and then click on the First Aid tab. You’ll be asked if you want to run First Aid on your hard drive, so click Run .

first aid

Method 10 – Reinstall OS X

This may sound a little extreme, but it’s kind of similar to how you have to reinstall Windows every year or so because it becomes so bloated. Unfortunately, OS X suffers from some of the same issues, especially if you have always kept upgrading to the latest version of OS X without doing a clean install.

I upgraded from Mountain Lion to Mavericks to Yosemite to El Capitan before doing a fresh install of El Capitan, which made things significantly faster. It’s definitely worth a shot because it also made every other app load a lot faster too.

Those are about all the possible solutions I could find to fix a slow Safari problem. If you have any other suggestions, feel free to let us know in the comments. Enjoy!

Why Is Safari So Slow? (5 Reason & What To Do)

Safari is one of the best Internet browsers that is currently available, and it’s known for its reliability. However, that doesn’t mean that it always runs smoothly. So, why is Safari so slow?

If Safari is so slow that it barely runs, close as many tabs and background apps as you can. Disable Safari extensions and clear the history and cache to remove corrupted data so it runs faster. Make sure that at least 15% of your Mac or iPhone’s storage space is open because full storage can slow down Safari’s performance.

Switch users on your Mac to see if Safari still runs slowly. It may simply be a problem with your user account having too much data. Follow along as we explore why Safari is so slow and see how you can fix it.

Table of Contents

Why Is Safari So Slow on Mac?

Poor wi-fi connection.

Your Wi-Fi connection is the first thing you should check if Safari is so slow on Mac that you can’t search anything. Safari will be slow even if you have Wi-Fi but the connection is weak. If your Wi-Fi keeps going in and out, simply unplug the router and modem for 30 seconds and plug them back in to reset them . 

Contact your Internet service provider or switch to cellular data if the problem continues.

why is safari browser slow

Corrupted Cache

Safari will run slow on your Mac if the cache is bloated and corrupted. Safari takes on plenty of data each day you use it, and some of it may be corrupted. Whether you have corrupted data or have simply gone years without clearing the cache, Safari will continue to run so slowly if you don’t clear it.

Once the Safari cache is full, the browser won’t be able to add and process new website information properly. Luckily, you can quickly clear the cache data on Safari under the History tab. Click the history tab to pull up the drop-down menu, then select Clear History and Clear Data.

Ideally, you should clear the cache on Safari once per month to ensure a smooth performance .

Safari is Outdated

If Safari is so slow that it’s a chore to browse, then it may be because the browser is outdated and needs an update. Apple typically releases updates for Safari up to 6 times per year . Safari updates are lumped in with the standard macOS updates that introduce and refine features on your Mac.

To install the latest macOS update, click the Apple icon on your Mac’s menu bar. Scroll down, select “System Settings”, and choose “System Update”. Make sure there is enough space on your Mac to install the update. This should improve your Mac’s performance and Safari’s performance speed.

User Account Error

Do you have multiple user accounts on your Mac? If so, you may want to check to see if Safari is so slow on the other users’ accounts. Much like how Safari’s cache can become corrupted, a specific user’s account on a Mac can become corrupted as well.

This happens over time when you browse Safari extensively and install extensions and apps that aren’t approved by Apple . Use another account to see if Safari runs smoothly. If so, return to the original user page with the slow Safari speed and open the Spotlight app.

Click the Disk Utility tab at the top of the page, scroll down, and select “First Aid”. Next, click “Repair Disk” and wait for your Mac to perform the repair. This should get rid of corrupted data and patch the user account so Safari won’t run as slowly.  

Extension Problems

Do you run Safari extensions on your Mac? If so, that could explain why Safari is slow, especially if the extensions aren’t optimized for a Mac . It’s hard to tell which extensions cause the problem unless you use an external app like CleanMyMac X and OS Mac Cleaner .

You can use these apps to cycle through apps and extensions to find out which ones are problematic. Refer to the information on the program to see which extension is causing the problem and delete it right away to boost Safari’s performance.

Too Many Open Tabs

Sure, Safari lets you open up to 500 tabs, but that doesn’t mean you should . The more tabs you leave open, the slower Safari will run on your Mac. Ideally, you should only leave a few tabs open at once if Safari is so slow that it’s hard to browse.

The advertisements and background activity from the tabs you leave open will slow down Safari’s performance. Close any tabs you are done with and continue to browse.

Excessive Background Activity

Just like how too many open tabs will slow down Safari, excessive background app activity can cause problems as well. Macs and iPhones must work extra hard to keep up with the processing demands when there is too much background activity. Close apps that you aren’t currently using so the processor can focus on Safari tabs and apps that you must use .

Search Suggestions Lag

The search suggestions Safari feature is useful when browsing the web, but it can also cause lags in some cases. If Safari runs slowly when search suggestions appear, you must disable the feature. Open Safari, click Settings, select Search , and tap the box beside “Include search engine suggestions” to disable the feature .

Low Storage

Whether it’s an iPhone, Mac, or MacBook, Apple devices cannot perform at their full capacity when the storage is too low. You should leave up to 15% of your Mac or iPhone’s storage open at all times to ensure quick operating performance and Safari speed . Remove apps that you don’t use often and delete old messages and pictures to free up as much space as possible.

So, Why Is Safari Running Slow?

Close as many tabs as possible and clear the cache and browser history if Safari is too slow. Disable extensions that aren’t approved by Apple and install the most recent macOS update to increase Safari’s speed. It also helps to close background apps and disable search suggestions if Safari is so slow that you can’t browse the web.

Whether you use the Safari internet browser for your everyday work, school work, online shopping, or simple internet browsing, having it work slowly can be extremely frustrating. This is completely understandable, but don’t worry we are here to help!

As someone who frequently helps people fix up their slow Macs, I can say from experience that Safari can often be the cause of a lot of problems. But the good news is that you don’t have to put up with Safari running slowly—there are a few quick troubleshooting tips you can use to get back in business.

Let’s explore why Safari is running so slow on your Mac and how you can fix it.

Table of Contents

Key Takeaways

Solution #1: verify your internet connection, solution #2: force quit safari, solution #3: update macos, solution #4: close excessive tabs, solution #5: disable extensions, solution #6: turn off icloud private relay – icloud+ only, solution #7: disable search engine suggestions, solution #8: disable autofill, solution #9: update dns server, solution #10: run first aid on ssd , safe mode – intel mac, safe mode – apple silicon mac, solution #12: use a 3rd-party web browser cleaner, final thoughts.

  • Safari has many features that attempt to either help you as the user or make the experience faster. Unfortunately, Safari can sometimes get bogged down.
  • Your internet connection should be one of the first things you check. Make sure everything is functioning properly here.
  • You can get Safari out of a jam by Force Quitting , and reopening.
  • If that doesn’t work, you can check your extensions , your iCloud Private Relay , and Autofill to ensure that your Safari is running as fast as possible. 
  • The DNS server can sometimes cause issues with Safari running slowly, so make sure that it is updated. 
  • If none of that works, you can also check to make sure your boot drive and your startup options are working properly. Run First Aid on your SSD and boot into Safe Mode to finish troubleshooting.

While Safari is preinstalled on your Mac and is updated using macOS, this doesn’t mean that it will always work perfectly. When Safari runs slow on your Mac, it can put a damper on your whole experience. You end up waiting on your computer and getting frustrated. So, what is causing this? And how can you fix it?

Here are some ways that we can hopefully get your Safari speed up.

This may sound obvious, but you may be surprised how easy it is to overlook losing your internet connection or other connection problems. Safari may not be working or may be running extremely slowly because of a faulty internet connection. 

There are multiple items that could affect your internet connection. Be sure to verify all of the following: 

  • You have full internet connectivity from your internet provider (if you are able to reach it, is a good way to determine if your internet is working to its fullest capacity).
  • Your modem and/or router are in working condition (the lights on the device will help you determine this. Look at or find the owner’s manual for your device if you have questions)
  • There are not too many devices on your network (I would recommend taking off some that you may not think of and are not currently using, such as phones, tablets, gaming consoles, and smart home devices).

By force quitting the Safari application , we are forcing any processes that may be stuck to stop. This can help Safari fully restart and stop trying to load something that may not be properly loading. To force quit Safari, take the following steps:

Press the Command-Option-Esc keys simultaneously on your keyboard.

Choose Safari from the menu and choose Force Quit .

Click on Force Quit to confirm.

As we have briefly discussed earlier, Safari is an application that is fully managed by Apple and updated along with macOS. So, if there is a problem with the Safari application itself, it is likely that Apple already knows and has released a patch to address it. 

To ensure your Mac is up to date with the latest version, take the following steps:

Using the Apple Menu, choose System Settings from the drop-down.

why is safari browser slow

Navigate to General on the left, then Software Update on the right.

why is safari browser slow

If there is a software update available, choose Update Now and follow the onscreen prompts to update macOS.

why is safari browser slow

If you are someone who never closes your browser tabs and has dozens of pages open at once (like I am guilty of doing most of the time), then I would suggest closing a good amount of them to get Safari working at a better speed. 

Having a large amount of tabs open, even ones that are not currently in use, uses not only a lot of processing power but also a lot of Random Access Memory (RAM) . 

Both of these items have a large impact on how the applications on your Mac run and can cause the Safari application to slow down significantly. So, close all possible tabs.

Extensions, also known on some internet browsers as plug-ins can be very helpful features. The most popular of these are ad blockers, coupon finders, and grammar checkers. If you use any of these or others, it is possible that they could be slowing down your Safari. 

It is also possible that extensions could have been inadvertently downloaded from the internet and enabled themselves. Check to make sure that there are no unrecognized extensions or an excessive amount of extensions enabled. 

With Safari Open, click the Safari menu and Settings from the drop-down.

why is safari browser slow

On the top, choose Extensions .

why is safari browser slow

On the left, the blue check marks indicate that the extension is enabled. Click these to show the gray checkbox and disable the chosen extensions. 

If you find any extensions that you do not recognize, select them on the left (it will be shown in blue) and click uninstall on the right. Follow any onscreen instructions to finish uninstalling. 

While iCloud Private Relay is a convenient and easy safety feature, however, it requires that your internet browsing passes through Apple servers prior to reaching your computer. This means that it could slow down your internet speed. 

Click the Apple Menu and System Settings .

why is safari browser slow

On the left, click your name, and on the right click iCloud .

why is safari browser slow

Scroll down to the iCloud+ features and ensure that Private Relay is turned off. If it is not, click on it and click the slider to turn it off. You may be asked to confirm by clicking “ Turn off iCloud Relay .”

why is safari browser slow

Search engine suggestions are a predictive feature when you are using Safari. They are designed to predict what you may be searching for and help you to find it easier. However, it is possible that they can be slowing down your Safari. Take the following steps to check:

With Safari open, choose the Safari menu and Settings.

why is safari browser slow

In the Search tab at the top, deselect the “Include Search Engine Suggestions” check box. It will show as a gray box when it is deselected.

why is safari browser slow

Another Safari feature, while helpful when it works properly, can also slow down the application is the Autofill feature. Autofill sometimes has a hard time accessing the information and may cause Safari to freeze. 

In Safari Settings (described how to reach above), Choose the Autofill tab at the top. Deselect all the Autofill features below. The items are deselected when they show a gray box instead of a blue checkmark.

why is safari browser slow

A Domain Name System Server (DNS Server) is a program that tells your computer and the internet what IP Address your computer or a website is using. By updating your DNS server you can not only improve your internet speed (and therefore your Safari speed), you can also improve your security. 

Some of the most popular DNS Server IP Addresses are those for Google,, and The DNS Server is allegedly considered to be the fastest in the world (though I am not confident in how or when that was recently confirmed). 

To update your DNS server, take the following steps:

Choose the Apple Menu and System Settings .

why is safari browser slow

On the left, select Network , and on the right, select Details under the Wi-Fi section.

why is safari browser slow

On the left, choose DNS . On the right, use the + button to add any of the DNS Servers that we have discussed (or others you may have found in your search). 

Note : it is OK to have more than one DNS Server—if one is down, your computer will use another one in your list.

Your Solid State Drive or SSD is a critical piece for the speed of your Mac. If all the other fixes up to this point did not work, it is possible that there may be an error on your SSD. First Aid will automatically check and fix most errors related to the formatting of your SSD. 

Open Disk Utility in Launchpad.

why is safari browser slow

Choose First Aid and follow the onscreen instructions.

why is safari browser slow

Solution #11: Boot in Safe Mode

Lastly, Safe Mode is a great way to determine if you are having further issues that are causing Safari to be extremely slow. Safe Mode disables your startup settings and features and any third-party items. If your Safari is running slowly for either of these reasons, you will be able to see using Safe Mode. 

Take the following steps to boot into safe mode, depending on which type of Mac you have:

  • Restart or turn on your Mac and press and hold the Shift key.
  • When the login window appears, you can release the key and login.
  • You may be asked to log in again, do so. You will see Safe Mode in the menu bar if this was successful.
  • Turn on your Mac and press and hold the power button until you see the Loading Startup Options screen.
  • If asked, select a volume.
  • Press and hold the shift key and click Continue in Safe Mode. Your Mac will automatically restart.
  • If successful, you will see Safe Mode in the menu bar.

Sometimes Safari doesn’t work properly when you have too much junk on your computer. A good 3rd-party application like CCleaner or CleanMyMac X can work wonders to optimize your system by getting rid of junk, including things like browser data and temp files.

CCleaner for Mac , for example, has a Browser clean-up tool that automatically scans and removes browsing data, caches, temporary files, cookies, and other tracking data.

why is safari browser slow

This can go a long way in speeding up Safari, and even helping out the rest of your computer too. While there is a paid version of the software, you can get quite far with the free version. So, it is worth a shot if you want an easy solution to Safari running slowly.

We have covered a lot of ground and talked about a lot of different options that could be causing your Safari Application to be slow. We first explored the more simple options, such as your internet connection being down, your Safari application needing to be updated, having a lot of tabs open, and clearing history. 

Your extensions possibly cause loading problems, your iCloud Private Relay, Search Engine Suggestions, and Autofill are also things you should check. If all else fails, you should look at two pieces of your Mac that could be affecting Safari as well, your SSD and the startup options.

If the rest of your Mac seems to be running fine enough to download another application, you could try a 3rd-party tool like CCleaner to clean up browsing data and other junk that could slow down Safari.

Safari has become very slow, lagging and not loading pages

In the past couple of months I've found Safari incredibly slow, either not loading or hanging on pages etc, and its getting worse. Mostly its a question of the blue line at the top just stopping a quarter or halfway in; occasionally the grey screen comes up to say it couldn't connect to the server. It seems to happen most on facebook but now it's happening almost every time I use my machine. If I reload the page a few times this often works so it appears to be a constant but temporary problem. I've tried other browsers but they seem to have the same issue. My internet speed tests show excellent speeds are available and the problem is the same whether I'm connected via ethernet or WiFi (same issue happens with my desktop Mac as well as my laptop). I've deleted cookies, emptied caches, even changed the DNS server and renewed the DCHP lease. etc. You can probably tell I have a limited understanding of such things so I'm at a loss what to do. Is it something to do with me not having enough memory on my Mac?

It has nothing to do with memory.

Force Quit Safari ( command + option + esc keys). Then restart Safari holding the Shift key.

Turn off Safari extensions in Safari > Preferences > Extensions > un-checkmark all extensions.

Empty Caches. You can either choose Safari menu > Clear History Or, if you do not want to remove History go to Safari menu > Preferences > Advanced and check the “Show Develop Menu” in Menubar. Then, on that menu > “Empty Caches”.

Hi, thanks for the response - I have done all these things and although re-starting always improves it for a time, it always begins to slow down again shortly afterwards. I've looked at those other links and beyond (which is where I got the advice re: DNS etc) and no luck either. I've just seen a site where they've advised deleting everything to do with Chrome so I've just tried that and restarted - so far, so good. If it solves anything I'll let you know.

The instructions to do so look a little scary to someone as technically challenged as me - but I'm guessing they're worth

doing? Any advice before I start??

Some other suggestions If the above doesn't work.

Go to Finder and select your user/home folder. With that Finder window as the front window, either select Finder/View/Show View options or go command - J. When the View options opens, check ’Show Library Folder’. That should make your user library folder visible in your user/home folder. Select Library/Caches/ and move it to the trash.

Go to Safari Preferences/Extensions and turn all extensions off. Test. If okay, turn the extensions on one by one until you figure out what extension is causing the problem.

If that doesn't work, try running this program in your normal user account , then copy and paste the output in a reply. The program was created by etresoft, a frequent contributor. Please use copy and paste as screen shots can be hard to read. On the screen with Options, please open Options and check the bottom 2 boxes before running. Click “Share Report” button in the toolbar, select “Copy Report” and then paste into a reply. This will show what is running on your computer. No personal information is shown.

Hi, its been a while but the issue persists! After removing all the 'cleaning' apps etc its been fine for a while but tonight Safari was barely usable - pages were not loading at all and I kept getting the grey screen saying it couldn't connect to the server. I'm at my wits end - I'm pasting one last EtreCheck, if you or anyone could tell me if there is anything else I could do I'd be really grateful!

If you are still using 10.13.2, try updating to 10.13.3, which will give you Safari 11.03.

Try running the combo update. It installs all previous updates plus the new one, which can replace any files that may have become corrupted.

Many thanks for the advice. I only installed memory clean, Sophos etc after experiencing these problems but it's good to know they might not be necessary. I'll do the clean up - is there any indication from the report why I might be having these issues? The issues with pages not loading/ lagging/ not connecting is just getting worse and the only thing that solves it temporarily is rebooting my machine....

How to Troubleshoot Safari if It’s Running Slow on Mac

why is safari browser slow

This article shows how you can fix the Safari browser if it is slow on your Mac. The purpose is to help speed up Apple’s Safari or determine why it is running slow. If you are experiencing one of the following issues, you can use this article to address your problem:

  • Safari is so slow and seems frozen.
  • Websites are taking a lot of time to load or videos are lagging.
  • A spinning beach ball frequently keeps appearing when attempting to browse the Web.
  • Clicking the Safari options (history, bookmarks, etc) temporarily causes Safari to freeze or become sluggish.

Safari Slow

There could be many reasons why you experience this issue. Follow the steps below:

1. Is the Mac up to date?

Ensure that your Mac is running the latest versions of the macOS version . Safari is a built-in app and the macOS software includes Safari. This means that updating macOS will also update Safari. You can go to System Preferences > Software Update to check for updates. And if there is an update, click the Update Now button to update your Mac.

Update Mac

2. Is it your Internet connection?

You may feel that Safari is sluggish because you may have a poor or unstable connection to the Internet. Use another browser (Chrome, Firefox, etc) to visit a website. Or try using multiple devices in your home. Do you still experience that your browsing experience is slow? If your answer is yes, then the problem may be your connection. Is the slowness just with one website or with all of the websites you try to visit? If the problem is with just one website, then the problem is that website. However, if all of the websites appear to be slow on all devices and/or using different browsers, the problem may be, again, your connection. If this is the case, try:

  • Ensure that your Mac has the latest version of macOS (System Preferences > Software Update).
  • Turn off your Mac (Apple menu > Shut Down), do not turn it on yet.
  • Restart your modem/router. Simply unplug it from power, wait 30 seconds and then plug it back in.
  • Wait for your modem/router to fully function (ensure that all of the indicator lights are on).
  • Turn on your Mac by pressing the power button.

  • How To Reset Network Settings On Mac

3. Too much cache? Clear your cache on Safari on your Mac

As you use Safari to visit websites, cache data will accumulate and this can possibly slow the browser down. Clearing the cache on your Safari browser will ensure that it’s working smoothly and efficiently. The Safari cache is a pile of temporary website data. Here is how you can clear cache in Safari on your Mac:

  • Open Safari.
  • Click Safari > Preferences.
  • Click the Advanced tab.
  • Check the box next to the “Show Develop menu in menu bar” option. Now a new menu item called Develop will appear.
  • Now exit Preferences.
  • Click Develop and Empty Caches.

Safari Develop menu

4. Are your extensions causing this?

An extension or add-on may cause this problem. Do you have these installed? If your answer is yes, try the following:

We can turn off Safari Extensions temporarily to see if they are causing this:

  • In Safari, click Safari > Preferences.
  • Click Extensions.
  • You will see your installed extensions.
  • Turn all them off by deselecting the checkboxes.

Now check Safari. Is it faster now? If turning off extensions resolves the issue, now determine the problematic extension that is causing this issue. Turn them back on, one by one, until you find the problematic extension. After each extension, you turn it on, test to see if the problem has recurred before turning on the next extension.

Safari Extensions

5. Safe Mode

Restart your Mac in Safe Mode . Safe Mode will clear some system caches. This can improve Safari’s performance. The steps will differ depending on the Mac type you have: Apple silicon or Intel. If you do not know, go to the Apple menu > About this Mac.

Apple silicon:

  • Turn off your Mac.
  • Press and hold the power button until the startup options window appears.
  • Click your startup disk.
  • Press and hold the Shift key and click “Continue in Safe Mode.”
  • Turn on your Mac and quickly press and hold the Shift key.
  • Release the Shift key when you see the login window.

Your Mac is in Safe Mode . Test Safari. Then exit Safari (just restart your Mac). Then test Safari again.

Safari Too Slow on Your iPhone? 4 Ways to Speed It Up

Are webpages taking forever to load in Safari? Follow these troubleshooting steps to resolve your speed-related issues.

Safari is the native browser on Apple devices. While it's usually fast, sometimes Safari can be slow or laggy. When this happens, it can be bothersome, and some might even download another third-party browser.

If you're noticing that Safari is running slow on your iPhone, there are several things you can do to speed it up again. Give these tips a try, and hopefully, Safari will be at full speed in no time.

Check Your Internet Speed

Before passing the blame on Safari, it might be a good idea to check your internet speed. That way, you can make sure Safari is the issue and rule out anything else before continuing.

If you're connected to Wi-Fi, open another computer or device on the same Wi-Fi network, then head to Speedtest's site and check your internet speed. You won't want to do this on your iPhone, as Safari issues can slow your connection time, giving you a false negative.

If your internet speed is fast, then Safari is the issue, and it's time to fix it.

1. Close All Your Safari Tabs

Safari can usually handle a lot of bandwidth and keep many pages open. However, some websites drain Safari data. By closing all the currently open tabs, you can confirm if one of the open websites was using too much data.

To close all the tabs on Safari, open Safari and hold the Tab button in the bottom right-hand corner. A prompt will appear for you to close all the tabs. Once this appears, hit Close All Tabs . Then, give Safari a try again.

2. Clear Your Browsing History and Data

If clearing the tabs didn't fix the issue, you can reset Safari and clear up the cache, speeding it up in the process. To clear Safari, head to Settings > Safari > Clear History and Data .

Once you do this, relaunch Safari and see if it's loading up pages quickly enough. If it's faster for a little while but begins to slow down again, proceed to the next tip.

3. Check Your iPhone's Storage

If your iPhone storage is almost full, that means it can't handle much else. Safari, like most apps, uses device storage to store data from the app. And low storage means Safari won't have enough memory to work.

This is why some users find Safari temporarily faster once they clear their browsing history and data. However, some users might have used so much storage that Safari might not even speed up when you clear the cache.

Luckily, it's easy to check if this is an issue. All you need to do is head to Settings > General > Storage and see how much space your iPhone has used. And if it's almost full, you might have to delete some large files.

However, if you don't want to lose precious data, consider signing up for a paid iCloud plan .

4. Reset Network Settings

When all else fails, you can reset your iPhone's Network Settings. Doing this will reset all network-related connections on your iPhone, hopefully speeding up Safari in the process. Head to Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings to do this.

Once you do this, you'll need to set up your network connections again. This means re-entering your Wi-Fi passwords. However, it can clear up a lot of bugs, so it is worth a try if all else fails. You can also reset your iPhone to factory settings as a last resort.

Browse Seamlessly in Safari

Safari comes pre-installed on all Apple devices, including the iPhone, iPad, and Mac. And since it's the native browser, it works seamlessly across all your apps and Apple devices.

While switching to a third-party browser like Chrome might seem tempting when Safari is slow or lagging, you'll miss out on a seamless experience. So, it's worth taking the time to fix whatever issue you're facing.

Safari in my experience has intermittent issues affecting loading of web sites. Is it a compatibility issue or something on the web sites that doesn’t play nice with Safari? That is possible since many say other browsers are not affected. This would rule out the OS or hardware or network. But would place the focus on Safari as the issue. Since Safari is purely a Apple OS boy browser. It could be a case that Apple is not following certain standards or adopting them as other browsers have.

Slow Safari on iPhone? – 11 Ways to Fix

Safari is a browser app that comes with iPhone as part of iOS. This is a default browser iPhone to open links from Mails, Messages and other apps. Though Safari offers useful features like tab grouping, voice search and extensions, the problem comes with the loading speed of webpages. If you are stuck with slow Safari on iPhone, here are some options to improve the performance of the app.

Note: Similar to iPhone, MacBook also comes with a Safari browser app as part of macOS. If you are looking for improving Safari performance in Mac, then check this article .

Safari Settings Page in iPhone

iOS offers a backend page for each app where you can finetune available settings and optimize performance of the app. You can access the Safari browser’s settings page by tapping on “Settings” app and then navigating to “Safari” section. Most of the below explained fixes are available within Safari settings page, though few settings can be accessed within the app or from other locations. Hence, we recommend you going through the Safari settings page and understand the functions before tweaking.

1. Close All Open Tabs – Auto Schedule or Manual

Closing all open tabs is one of the first things to do when you notice the browser loads webpages slowly. Most smartphone users continue to open new tabs and access webpages without closing previously opened tabs. Though Safari will work fine with 20 to 30 open tabs, it will either crash or work slow when you have more than 30 tabs. Unfortunately, simply closing the app will not close open tabs and they will be in open state when you launch the browser again. The problem is that Safari will try to refresh the webpage on the open tab whenever you launch the app. This will not only slow down the performance but also waste your time in viewing same old page which you have already visited. You have the following two options to deal with open tabs:

  • Manually closing tabs – simply tap on the tabs icon in Safari and close all your open tabs.

Close Open Tabs in Safari

  • Scheduling automatic closure of tabs – go to Safari settings page and tap on “Close Tabs” option showing under “Tabs” section. Select one of the schedules from the list as “After One Day”, “After One Week” or “After One Month”. This will automatically close all your open tabs and keep the browser clean as per the selected schedule.

2. Restart the Browser and iPhone

Restarting is one of the unharmful solution that you can try with any software problems.

  • Restart Safari – when you are in Safari app, swipe up from the bottom to open App Switcher. Hold and move the Safari screen up to close the app. Remember, this will not close open tabs and you should follow the above-mentioned methods for closing your open tabs.

Close Safari App in iPhone

  • Restart iPhone – go to “Settings > General > Shut Down” and swipe the “Slide to power off” button to shut down your iPhone. After that, press and hold the side power button to restart .

3. Disable Experimental Features

Apple silently enables some experimental features with Safari app in iPhone. Though these are experimental features, most of them are enabled by default. Go to Safari settings page, scroll down to the bottom and tap on “Advanced” option. Tap on “Experimental Features” and disable all or the suspected items. Do not worry if it creates some problem, you can scroll down to bottom of the “Experimental WebKit Features” page and select “Reset All to Defaults” option. This will help to reset all the features like before.

Disable All Experimental Features in Safari iPhone

4. Disable Safari Suggestions and Preload

Getting automated suggestions can easily annoy when you type in Safari app. For example, preloading option will force Safari to check in your history and bookmarks whenever you try to open a website in the address bar. This will slow down the browser when you have huge list of reading list, bookmarks and history. You can try disabling the following automated suggestions from Safari settings page and check whether it helps to load pages faster.

  • Search Engine Suggestions
  • Safari Suggestions
  • Preload Top Hit

Disable Suggestions in Safari iPhone

5. Stop Processes Running in Background

The processes running in background can easily affect the entire performance of your iPhone. It could be an app download from other device, an app update or a content refresh in apps. For example, if an app with 1GB size is getting updated in the background, obviously it will affect the performance of other apps like Safari which you may be using in the frontend. You can disable automatic updates and background app refresh using the following instructions:

  • Automatic App Downloads – go to “Settings > App Store” and disable “Automatic Downloads” for apps and app updates. Also make sure this option is disabled for “Cellular Data” for saving your mobile data usage.

Disable Automatic App Updates in iPhone

  • Background App Refresh – go to “Settings > General > Background App Refresh ” section and choose “Off” for “Background App Refresh” option.

6. Delete Browsing History

Whenever you visit a webpage, Safari will cache its files in phone’s storage . The cached content includes all static files on the page like images, CSS and JavaScript which are required to load the page. In theory, this caching should help in speed up the loading when you visit the same page next time or other pages on the same website. However, the size of cached data will become huge thus affecting the overall performance of the browser. In addition, cached data can also create problems when the website owner changed its design, moved server to another location or redirected the page to another URL. Therefore, it necessary for you to clean up the cached website data in Safari in regular intervals.

  • When you are in Safari settings page, scroll down and tap on “Clear History and Website Data” option. You will see a pop-up from bottom and select “Clear History and Data” to confirm deleting all cached data from the browser.
  • Tap on “Advanced” option and then select “Website Data” to view all stored website data in Safari. Generally, clearing browsing history will delete all these data as well. Otherwise, you can tap on “Remove All Website Data” option to delete them manually.

Clear Safari Browsing History in iPhone

Remember, deleting history or website data will NOT delete your bookmarks, reading list or passwords. However, you may feel the websites are loading slower when opening first time as the browser needs to request all static files from the server without previously stored cache. This will come to normal when you start using the browser visiting your favorite pages. In addition, you can also use private browsing mode to speed up webpage loading time in Safari.

7. Run Software Update

As mentioned, Safari is part of iOS and gets the update along with the iOS updates. Sometimes, Apple will release bug fixes for Safari app as part of the iOS release. Go to “Settings > General > Software Update ” section and check whether you have any pending updates. You can read the release notes to understand if the release has any Safari related fixes. Tap on “Download and Install” option to get the latest iOS version and check if that helps to improve the performance of Safari app.

Install Latest iOS Update

Remember, it works other way round that sometimes an iOS update can affect the performance of Safari app. This is especially the case with the release of major iOS versions where the app will get new features. Make sure to disable automatic iOS update and always wait for a week time to get feedback from users whenever Apple releases new iOS versions. If there are any major problems, Apple will release a patch immediately and you can update the iOS after understanding there are no major glitches to default apps.

8. Reset Network Settings

Sometimes, resetting your network settings can help to speed up the browsing in Safari.

  • Go to “Settings > General” section.
  • Tap on “Transfer or Reset iPhone” option.
  • Select “Reset” option and then select “Reset Network Settings” from the list.
  • Enter your passcode and wait for the process to complete.

Reset Network Settings in iPhone

This will reset all your network related settings like Wi-Fi password . Therefore, make sure to keep the password ready for reconnecting again.

9. Change to Public DNS

Resetting network and deleting browsing history will help to fix the Safari problems from your side. However, this will not fix if your ISP filter the browsing or using corrupted DNS setup. Since iPhone by default uses DNS from your ISP, any problem at the ISP end will impact your browsing experience also. The best solution to overcome ISP related problems is to change the default ISP provided DNS and public DNS from Google or OpenDNS.

  • Open “Settings” app and tap on “WLAN” option.
  • Tap on your Wi-Fi network that is currently connected.
  • Scroll down on the page and select “Configure DNS” option.
  • By default, this should have “Automatic” setting and select “Manual” option.
  • Delete existing DNS servers and tap on “Add Server” option.
  • Add and then (these are Google Public DNS server IPs) and tap on “Save” option showing on top right corner of the screen.

Configure Manual DNS in iPhone

Now open Safari and check if the webpages are loading faster with new DNS servers. Similarly, you can tap on “Configure IP” and change to static IP address which you can obtain from your ISP.

10. Use Proxy or VPN

If your ISP really throttles or blocks websites or services, it could make Safari slower. For example, countries like China completely blocks services from Google, YouTube, Facebook and Twitter. In this case, opening a page with a YouTube video will load forever till the time the request for video times out . The solution here is to use a proxy server or VPN app to unblock the free internet.

  • Proxy – when you are on the Wi-Fi settings page, scroll down to bottom and tap on “Configure Proxy” option. On the next screen, enter your proxy server details and save the changes.
  • VPN – you can find plenty of reliable VPN apps in App Store. For example, ExpressVPN is a premium app which you can try to unblock free internet. When you open the app, it will install the configuration profile and allow you to bypass the ISP connection.

11. Blocks Ads and Trackers with Content Blockers

Nowadays, almost all websites use advertisements, analytics and social tracking. The problem is that all these features will slow down the browser and affect the loading time, Fortunately, Safari app will automatically block trackers and show you the privacy report on the home page whenever you open app.

Safari Privacy Report in iPhone

If you want to block advertisements , then you can use reader mode or use ad block extensions from App Store. These extensions will use content blockers feature in Safari and help to block intruding ads on the pages thus speed up the browsing experience.

Final Words

We hope the above options helped to fix slow Safari on iPhone and speed up your browser. it is a good idea to schedule automatic closure of tabs and delete browsing history in regular intervals. If none of the above options work, then you can try resetting the iPhone as a last resort. This will delete all your customizations and reset the phone to factory settings. So, do this only if you are prepared to setup your iPhone from the scratch. Otherwise, you can always switch the default browser to Google Chrome, Firefox or Edge and remove the Safari app from your phone .

Why is Mac browser running slow and how to fix it?

If in the past few months you’ve noticed that your web pages are loading slowly, it’s likely that your Mac is in need of some maintenance. In this article, you will learn why your browser is so slow, how to solve slow browser issues, as well as how to speed up Chrome, Safari, or Firefox on your Mac.

1. Why is my Mac Browser so slow

In short, the most common reason for slow browser performance is unnecessary plugins, extensions, and panels that are either automatically installed with other applications or are third-party add-ons. In addition to slow performance, other browser problems can result in Google Chrome and Firefox, as well as Safari. The most vulnerable point of modern computers is the hard drive. Most users have a classic HDD with rotating platters. Every browser has cache files, which are stored on the disk. Therefore, all problems with slow performance have a root just in it. If you have not cleared your browser’s cache for a while, you will notice a significant improvement in the speed after cleaning it. Some users notice this and choose to clear the cache frequently. Thus, first of all, you should find out what makes your browser speed slow and what causes it sometimes to quit unexpectedly .

Pay attention to the following points to find out the reasons why is your browser so slow and how to speed up the Chrome browser, Safari browser or Firefox browser on a Mac:

✓ Browser’s Extensions

A large number of tools installed in the browser’s toolbar is convenient for a user, but the cumulative effect slows the browser’s performance. When a user installs programs on a computer, various browser extensions are installed, too. In this case, they may not be needed, and the inexperienced user may not even notice that something else is being installed.

Typically, most users don’t use all panels, but they affect the browser’s loading time and performance speed. As soon as a user collects several such panels on his computer, the first launch of the browser may take a minute or so. Well, this annoys us a lot. Thus, if you have too many browser extensions, you should analyze them and remove unused ones. Read our previous article to learn how  to remove browser extensions .

By default, when you install a browser, many plugins that are not needed are installed and activated as well. Also, some programs installed on your Mac automatically add their plugins. To find a list of your Mac internet plugins, go to the following path ~/Library/Internet Plugins. You can check which plugins make your browser slow. For this, create a new folder in Finder and move all the third-party plugins into it. Then check your browser’s performance. If everything is working well, then we were right. Add back one extension after another and check the browser’s performance. In this way, you can find the problematic plugin. If a “bad” extension is found, you can disable it, or even better, delete it.

Most modern websites use Java components. If you have not updated Java on your Mac for a long time, this can cause your browser to work poorly. To update Java to the latest version follow these steps: go to the official Java page → click to download Java for free → open the downloaded installation file → follow the on-screen instruction to install Java.

Some users rarely need Java and prefer to remove it entirely because Java has a significant impact, not only on the browser’s performance and speed but also on its’ vulnerability to various Trojans and viruses from the Internet. Perhaps after that, your browser will maintain a more optimal speed.

✓ Flash Player

If you use Safari, you can try to remove Flash Player. Actually, the famous Flash Player plugin from Adobe is not pre-installed on Apple’s computers. Despite this, millions of users install Flash Player because many Internet resources still use it for media content. We recommend that you delete or disable this plugin. It not only causes Safari to work poorly but also puts your Mac at risk of being hacked.

When you visit websites day after day, your browser collects its’ own database of addresses, texts, pictures and other information about these resources. Despite the fact that the browser cache is designed to speed up its performance, in rare cases, when the size of the database is too large, it can cause a slower loading time. In this case, you should try to clear the cache of your browser .

✓ Browser’s Update

Neglecting to update the browser routinely is another possible reason for slow performance. Open your browser, go to the Menu bar and select “About browser…” You will see a window with information on what version of the browser you have. If it is needed, click to update your browser.

If it is the real reason, then you should u ninstall your antivirus program or decide whether the security or page loading speed is more important to you.

Anyway, if Safari is slow and not working properly, you should try the following solutions to make the browser speed faster:

  • Check for software updates from Apple.
  • In Safari Preferences, choose to open tabs, not with the Top Sites but a blank page.
  • Clean the entire history (cache, cookies, …) or do a Safari reset .
  • Try to update Adobe Flash Player to the latest version or disable Flash . If you need to enable Flash, you can install a special extension for Safari, which allows you to watch the necessary video from Adobe Flash.
  • Clean up unnecessary Internet Plugins. The plugins are located in the Library folder. Some plugins can slow down Safari, especially the old ones which are not supported and do not work correctly with the latest version of the browser.

“However, the reason behind this is, the person who have Mac or iPhone they face any problem in Safari, they move to Google Chrome.

Instead, they should try to fix Safari complications”

looool. No, they should use whatever works. Safari has no excuse, I’m sorry.

PS: Yes I miss the handover and shared ios macos tabs too… but, a non-functional browser is a non-functional browser…

PS2: I am still wasting time with relogins from your fist solution… So you say I should reinstall Mojave… when there are other browsers that work just fine… again: looool

With Windows 7, Google was fast downloading. I have recently switched to an iMac and have been driven mad by the slowness downloading web pages – sometimes it sticks part way through and I get nothing. I switched to Bing – that was as slow. In desperation I tried DuckDuckGo. Pages are downloaded instantly. I have no idea why, but it work, so I’ll stick with it.

Solution 10: how do you reinstall Mojave? Thanks

For your information, I have restored Safari normal speed on Catalina by deactivating my Intego Netbarrier suite

I upgraded my MacBook Pro to Catalina a couple of weeks ago and all was good. Today I upgraded my MacAir and I basically can’t connect to the internet using the wifi that I used before to download Catalina and the same wifi that I am using on the Pro to find your website and to send this message. I tried deleting the cache and reopening Safari and restarting but still nada.

What’s up with that?

Are you frustrated with the sluggish performance of Safari on your iPhone? You're not alone. Many iPhone users encounter slow browsing speeds and unresponsive behavior while using Safari, the default web browser. This can be a major inconvenience, especially when you rely on your iPhone for various online activities such as browsing, shopping, and staying connected with friends and family.

The speed and efficiency of a web browser significantly impact the overall user experience. When Safari lags or takes ages to load web pages, it can lead to frustration and a less enjoyable browsing experience. Understanding the potential causes of Safari's slow performance and learning effective solutions to address these issues can greatly enhance your browsing experience on your iPhone.

In this comprehensive guide, we will delve into the common reasons behind Safari's sluggish behavior on iPhones and explore practical solutions to speed up the browser. By the end of this article, you will have a clear understanding of how to optimize Safari's performance, ensuring a smoother and more responsive browsing experience on your iPhone.

Let's dive into the factors that could be contributing to the slow performance of Safari on your iPhone and discover actionable strategies to revitalize the browsing speed and efficiency.

Common Reasons for Slow Safari on iPhone

Outdated Safari Version : Using an outdated version of Safari can significantly impact its performance. Newer versions often include optimizations and bug fixes that can enhance browsing speed and responsiveness. It's essential to regularly check for updates in the App Store to ensure that you are running the latest version of Safari on your iPhone.

Excessive Cache and Data : Over time, Safari accumulates a substantial amount of cache and browsing data, which can lead to slower performance. This buildup of data can clog the browser's functionality, causing delays in loading web pages and navigating through websites. Clearing the cache and browsing history can help alleviate this issue and improve Safari's speed.

Limited Available Storage : Insufficient storage space on your iPhone can also contribute to Safari's sluggish behavior. When your device's storage is nearly full, it can hinder the browser's ability to function optimally. This can result in slower page loading times and overall performance degradation. Regularly freeing up storage space on your iPhone can help mitigate this issue.

Network Connectivity Issues : Slow or unstable internet connections can have a direct impact on Safari's performance. When the network connection is weak or unstable, web pages may take longer to load, and browsing responsiveness can be compromised. It's crucial to ensure that you have a stable and fast internet connection to support Safari's optimal performance.

Heavy Website Content : Websites with extensive multimedia content, such as high-resolution images, videos, and complex scripts, can strain Safari's resources, leading to slower browsing speeds. These elements require additional processing power and bandwidth, which can result in delays when loading and navigating through such websites.

Background Processes and Tabs : Having multiple tabs open in Safari or running background processes can consume system resources, potentially impacting the browser's performance. Each open tab and background process adds to the overall workload on the device, potentially leading to slower browsing speeds and increased system resource utilization.

Software Glitches and Bugs : Like any software, Safari may experience glitches and bugs that can hinder its performance. These issues can manifest as slow loading times, unresponsive behavior, or unexpected crashes. Keeping your iPhone's operating system and Safari updated can help address known software-related issues and improve overall performance.

Identifying these common reasons for slow Safari performance on your iPhone is the first step toward optimizing your browsing experience. By understanding these factors, you can take proactive measures to address them and enhance Safari's speed and responsiveness on your iPhone.

Solutions to Speed Up Safari on iPhone

Now that we've explored the common reasons behind Safari's sluggish performance on iPhones, it's time to delve into actionable solutions to revitalize the browsing speed and efficiency. By implementing the following strategies, you can significantly enhance the performance of Safari on your iPhone, ensuring a smoother and more responsive browsing experience.

1. Update Safari and iOS:

Keeping Safari and your iPhone's operating system up to date is crucial for optimal performance. Regular updates often include bug fixes, security enhancements, and performance optimizations that can improve Safari's speed and responsiveness. Check for updates in the App Store and under "Settings" > "General" > "Software Update" to ensure that you are running the latest versions.

2. Clear Cache and Browsing Data:

Clearing Safari's cache and browsing history can help alleviate performance issues caused by accumulated data. To do this, navigate to "Settings" > "Safari" > "Clear History and Website Data." This can free up valuable storage space and improve Safari's ability to load web pages efficiently.

3. Manage Storage:

Regularly decluttering your iPhone's storage by removing unnecessary apps, photos, and files can contribute to improved Safari performance. Navigate to "Settings" > "General" > "iPhone Storage" to identify and remove unused apps and media files, creating more room for Safari to operate smoothly.

4. Optimize Network Connectivity:

Ensure that you have a stable and fast internet connection to support Safari's optimal performance. If using Wi-Fi, consider restarting your router or connecting to a different network if the current one is slow or unstable. When on cellular data, ensure that you have a strong signal for seamless browsing.

5. Limit Open Tabs and Background Processes:

Closing unnecessary tabs and background processes in Safari can help conserve system resources and improve browsing speed. To close tabs, tap the square icon in the lower-right corner of Safari and swipe left on any tabs you want to close. Additionally, regularly closing background apps running on your iPhone can free up resources for Safari.

6. Enable Content Blockers:

Consider using content blockers to prevent resource-intensive elements, such as ads and tracking scripts, from loading on web pages. This can significantly improve Safari's speed and reduce the strain on your device's resources.

By implementing these solutions, you can effectively address the common factors contributing to slow Safari performance on your iPhone. These proactive measures will help optimize Safari's speed and responsiveness, ultimately enhancing your overall browsing experience on your iPhone.

In conclusion, addressing the factors contributing to slow Safari performance on your iPhone is essential for optimizing your browsing experience.

The Best Way Yet to Measure Browser Performance">Speedometer 3.0: The Best Way Yet to Measure Browser Performance

Mar 11, 2024

by Ryosuke Niwa

As announced on today, in collaboration with other browser engine developers, Apple’s WebKit team is excited to introduce Speedometer 3.0 , a major update that better reflects the Web of today. It’s built together by the developers of all major browser engines: Blink, Gecko, and WebKit with hundreds of contributions from companies like Apple, Google, Intel, Microsoft, and Mozilla. This post is a deep dive into how the collaborative Speedometer project improved the benchmark’s measurements methods and test content.

To recap history, in 2014, the WebKit team at Apple released the Speedometer browser benchmark , designed to measure the responsiveness of websites and web apps.

The original Speedometer simulated user interactions in web applications, driving TodoMVC sample apps written using different JavaScript frameworks to add, complete, and remove todo items. It was unlike other DOM or web app benchmarks publicly available at the time. These older benchmarks were mostly collections of micro-benchmarks, and didn’t reflect how DOM APIs were used in real web apps, or how individual APIs interacted with the rest of the web browser engine. Speedometer quickly became an important tool for performance measurement and tuning not just in WebKit but also in other browser engines.

In 2018 the WebKit team, in collaboration with Google’s Chrome team, released Speedometer 2.0 , updated to use the latest frameworks and libraries available at the time. The Speedometer benchmark has since gained even more popularity among browser engines as a guide for optimization, and among independent testers and reviewers to compare different devices, operating systems, and browsers.

Today’s release of Speedometer 3.0 marks a major step forward in web browser performance testing. It improves the accuracy of measurement and measures the performance of a wide variety of contents.

Cross-Browser Collaboration

Speedometer 3.0’s release is a result of the collaboration among browser developers to improve the Web as a whole together. Much as Interop 2024 represents joint work to test and improve standards compliance, Speedometer 3.0 is a joint effort to test and improve browser performance.

Where previous Speedometer versions were developed as part of the WebKit project, Speedometer 3.0 has been developed and released under a joint multi-stakeholder governance model including the three major engine browsers: Blink, Gecko, and WebKit, and the repository has received hundreds of open source contributions since the original announcement in December 2022 . This collaboration better ensures fairness in measurement and workload composition. And together, the group created a shared vision for the benchmark.

Improved Test Harness

We’ve improved the way Speedometer measures runtime performance. Prior Speedometer versions measured the time to run a test script synchronously as “sync” time; and the time until a zero-delay timer scheduled at the end of “sync” work fires as “async” time, as shown in the following diagram:

In Speedometer 2, async time was measured as between when a timer is scheduled at the end of sync time and when the timer fires. That sometimes captures layout and paint and other tasks running after synchronous script execution but before the timer fires.

However, this method sometimes misses important work that browser engines do in response to script-driven changes, because synchronous tasks and the zero-delay timer are scheduled without considering the timing of rendering updates. It also didn’t capture any work frameworks delay until the next requestAnimationFrame (rAF) callback, a common technique in modern frameworks. The following diagram illustrates how important work could be missed by the time calculations.

In Speedometer 2, it was possible that requestAnimationFrame, layout, and paint to happen after the async timer had fired in some cases. In such cases, we fail to capture the time browser spends updating the rendering of a web page.

Speedometer 3.0 takes advantage of the fact that all browser engines have adopted the HTML5 event loop model for updating the webpage rendering. It measures test scripts within a requestAnimationFrame callback as “sync” time, and the time to fire zero-delay timer scheduled in a second requestAnimationFrame as “async” time:

In Speedometer 3, we schedule two requestAnimationFrame callbacks. The first one runs and measures sync time, and the second one schedules a timer to measure the async time. Because browsers are expected to update the rendering after invoking requestAnimationFrame callback but before running any other tasks, we always capture the time browser spends updating the rendering of a web page.

Because the zero-delay timer is now scheduled in a second requestAnimationFrame, it’s guaranteed to be fired after all the zero-delay timers scheduled during the synchronous portion of the test had fired. Thanks to HTML5’s event loop processing model, browser engines update the rendering of web pages after all requestAnimationFrame are called before the next zero-delay timer fires. These changes greatly improved Speedometer’s ability to accurately measure the runtime of synchronous work and asynchronous work browsers do in response to script that handles user events.

The test harness has also been rewritten to use modern JavaScript features like modules, native promises, let & const, async & await, and class syntax, which were not widely available at the time Speedometer 1.0 was first written.

Like its precursors, Speedometer 3.0 sums up the runtime taken to simulate user actions such as adding todo items, completing them, and removing them per each workload, and computes the geometric mean of the totals across different workloads. The final score is calculated as the arithmetic mean of the reciprocal of the geometric mean:

In Speedometer 3, each workload can have multiple sync and async times. The total time for all sync and async time is calcualted for each workload, and the score is calculated as the reciprocal of the geometric mean of the totals across workloads.

Adjustment to Score

Since Speedometer’s benchmark content was last updated in 2018, web browsers have gotten increasingly better at handling Speedometer content. Moreover, new hardware, such as Apple Silicon Macs, continues to push the boundary of what’s possible in computing. Where originally scores were scaled to be under 100, modern browsers now can score over 500 on the fastest devices. To make scores easier to compare and to make room for future improvements, we’ve adjusted the score so that a typical web browser will get a score in the 20-30 range to start out.

Updated UI Frameworks

Now let’s take a look at the test content in Speedometer 3. Like the past versions of Speedometer, version 3.0 includes TodoMVC-based todo apps that emulate adding, completing, and removing todo items. To better represent the modern Web, the most widely used JavaScript UI frameworks were identified from the HTTP Archive in March 2023:

In the order of popularity, React, Vue.js, React, Backbone.js, AngularJS, Next.js, Angular, Nuxt.js, lit-html, Knockout.js, Alpine.js, Marionette.js, Gatsby, Svelte, React Redux

The monthly downloads in NPM was also taken into account to find frameworks with high momentum:

In the order of NPM monthly downloads, React, React Redux, Next.js, Vue.js, Angular, Preact, lit-html, Backbone.js, Nuxt.js, Svelte, AngularJS, Gatsby, Alpine.js, Knockout.js, Marionette.js

Based on these data points, we’ve included the following JavaScript frameworks in our todo apps: Angular , Backbone , jQuery , Lit , Preact , React , React+ Redux , Svelte , and Vue . For each framework, the most commonly used version at the time was picked. Todo implementations written in vanilla JavaScript using ES5, ES6, and web components are also included.

Complex DOM Versions

In addition, Speedometer 3.0 includes “complex DOM” versions of some of the TodoMVC applications. In these complex DOM versions, each todo app is embedded inside a UI structure which mimics a web application with many deeply nested DOM nodes and plenty of CSS rules. Even though the benchmark still emulates the same set of operations, doing so in the context of more DOM elements and CSS rules adds work and captures additional performance bottlenecks.

In order to ensure the variety of performance scenarios to be tested, Speedometer 3.0 includes 6 simple DOM todo applications and 6 complex DOM todo applications.

Complex DOM workloads has ribbon menus, side bar tree view, search field, and other complex UI elements surrounding the todo app.

Broader Content

Together, these changes to todo apps dramatically improved the coverage of the benchmark. But Speedometer 3.0 takes it a step further and includes entirely new kinds of applications.

Speedometer 3.0 includes two test apps that mimic typical news sites, built using the popular single page application frameworks Next.js and Nuxt . It emulates user actions such as clicking on menu items and navigating to another page in the single page app setup.

News sites workload mimics a popular news site with navigation menu, hero images, headlines, and a summary of articles.

Speedometer 3.0 also includes four charting applications based on Observable Plot , chart.js , React stockcharts , and WebKit’s performance dashboards . Observable Plot and React Stockcharts are based on D3 and test manipulating SVG-based graphics. Chart.js and WebKit’s performance dashboards test drawing canvas-based graphics.

Charting workloads draw bar graphs of the number of airports in each U.S. state for example.

Finally, Speedometer 3.0 has added two text editing applications: a JavaScript code editor built with CodeMirror and a WYSIWYG editor built with TipTap . In both scenarios, it emulates the steps to create a new editable region, loading a large amount of text, and syntax highlighting or boldening text:

CodeMirror workload, for example, loads React's codebase and enables syntax highlighting

The addition of these new applications dramatically broadens the scope of what Speedometer 3.0 measures, and provide new opportunities for browser engines to optimize a broad spectrum of features like JavaScript, style, layout, graphics, and DOM.

Future Work

Today marks a remarkable milestone for the Web platform. Speedometer 3.0 sets a whole new standard for measuring web browser performance. As browser developers optimize their engines, this will expand the horizon of what Web developers can achieve in the years to come. Because the goal of the Speedometer benchmark is to reflect the real-world Web as much as possible, we’re expecting this benchmark to evolve over time. We’ll be regularly updating the list of frameworks to be tested, and periodically updating the tested framework’s versions to reflect the real world usage. You can try Speedometer 3 benchmark on .

Spring Cleaning: Clear Your iPhone Cache

Give your iPhone a fresh start by clearing your browser cache.

why is safari browser slow

  • Adam has been covering streaming services since 2013 and wants to help people navigate the subscription creep in their lives.

why is safari browser slow

  • Apple software beta tester, "Helps make our computers and phones work!" - Zach's grandparents

A person using an iPhone

A clear cache keeps your browsing snappy.

Your  iPhone  can get cluttered, just like the rest of your home. No, I'm not talking about too many videos of your kids and pets, or too many memes saved to your camera roll. I'm talking about your browser cache.

CNET Tech Tips logo showing the outlines of multiple devices

If you're cleaning up your home for the spring, don't forget to spruce up your iPhone's cache, especially if your browsing starts to feel sluggish over time. It takes only a few seconds to keep your iPhone 15 or 15 Plus , iPhone 15 Pro or Pro Max or any other model moving as fast as possible. 

Browser caches are intended as a convenience, but without proper maintenance, they can turn into more of a hassle. Think of them like a table, counter or other flat surface in your home that starts as a quick place to leave and grab your keys but eventually turns into a cluttered mess where it's impossible to find anything. Your cache stores website data for faster retrieval the next time you visit, but if the design or content of that site changes, it can actually slow down your browsing or lead to bad formatting on the site. Clearing your cache is like clearing off the counter so everything is clean and easy to navigate.

Whether you use  Chrome , Safari or other browsers on your iPhone, your cache builds up that digital clutter over time. Clearing your cache gives the browser a new start, which can speed up your web surfing, even on  iOS 17 . (If you're trying to get your phone to run faster, try  managing your iPhone's storage .)

Website cookies are similar, except they store information about user data, rather than data on the website itself. Clearing your cookies gives you a chance to reset those preferences, which could improve your browsing experience. Note that clearing your cache and cookies will log you out of sites, which means you'll have to log into them again and reset any preferences. The upfront investment of that time can lead to a smoother experience down the road, and it can be a useful fix if you've recently changed settings that aren't being applied properly.

Here are step-by-step guides on how to clear your cache on your iPhone based on  the browser you use . 

How to clear your iPhone cache in Safari

Safari is the default browser on iPhones, and you can clear your Safari cache in a few short steps. Starting with iOS 11, following this process will affect all devices signed in to your iCloud account . As a result, all your devices' caches will be cleared, and you'll need to sign in to everything the next time you use them. Here's what to do.

1 . Open the Settings app on your iPhone.

2 . Select Safari from the list of apps.

3 . Go to Clear History and Website Data.

4 . Choose Clear History and Data in the pop-up box.

Then you're set!

What happens when you clear the cache? 

Clearing your cache removes the website data your phone stored locally to prevent having to download that data upon each new visit. The data in your cache builds over time and can end up slowing things down if it becomes too bulky or out of date. (My phone had about 150MB of data stored in Chrome when I checked.) Clearing that data gives sites a fresh start, which may fix some loading errors and speed up your browser. Clearing your cache also signs you out of pages, so be prepared to sign in to everything again. 

How often do I need to clear my cache?

Most people only need to clear their caches once every month or two. That's generally the point when your browser will build up a cache large enough to start slowing things down. If you frequent a large number of sites, you should err on the side of clearing your cache more often.

The best secure browsers to protect your privacy online in 2024


Web browsers have become flooded with ad-sponsored content, making browsers a key battleground for end-user privacy. While Chrome is the most widely used browser in the world, there are alternative browsers and ways to improve your security available to help you stay anonymous online.

Data is one of today's key ingredients for generating revenue. Online advertising companies can use web browsing histories to fingerprint individual browsers over time, creating shadow user profiles to reveal information including a user's interests, product searches, and more -- which can lead to targeted advertising. When you look for a privacy-focused browser, you will want to investigate how advertising trackers and cookies are managed, whether or not search histories are stored or shared, and whether or not the browser developer has a transparent privacy policy in place. 

Also:   The best VPN services (and why you need one to protect your privacy)

What is the best secure browser for privacy in 2024?

ZDNET experts have kept a finger on the pulse of the secure browser market for decades and many of us have tried and tested different options throughout the years. Brave is our top pick for the best browser for privacy based on its approach to user privacy, ad tracking prevention, privacy settings, usability, and speed. 

Below, you will find other recommendations for secure browsers that can protect your privacy -- not only from cyberattacks, but also from businesses that scrape, store, and sell your data. 

Best secure browsers for privacy in 2024

Best browser for privacy overall.

  • Not in the traditional online ad business
  • Privacy-focused by default
  • Chromium challenger
  • Some users report compute resource issues

Brave f eatures: Chromium-based | Blocks third-party ad trackers | Blocks cookies | Incognito windows | Onion routing | VPN | Off the record browsing

Brave is a Chromium-based browser that blocks ads, fingerprinting, and ad trackers by default.

Brave supports millions of users worldwide. The organization's business model relies on privacy-protecting ads that pay publishers and users when users pay attention to ads. The company is transparent about this revenue stream, and it is optional -- with users rewarded in crypto tokens if they opt in to ad viewing.

Brave has several privacy-enhancing settings, including options to block third-party ad trackers, upgrade unsecured connections to HTTPS, as well as block cookies and fingerprinting. Invasive ads and trackers are disabled, which the company says then improves loading times on desktop and mobile.

Also: The best web hosting services for building your dream website

Brave  removed Google code  from its Chromium to improve user privacy, including some account integration, background sync, and inline extensions. There is also a "Tor mode" available for use, which provides anonymized onion network routing. 

The browser developer also offers a VPN and firewall service which protects sessions even outside of the browser. Many users say the browser exceeds expectations, although others find some functionality, such as VPN connectivity, could use improvement. 

Brave also offers a feature called " Off the Record " (OTR) for users who may be victims of intimate partner violence. The browser developer says the feature "aims to help people who need to hide their browsing behavior from others who have access to their computer or phone."

Mozilla Firefox

Most secure browser for tracking protection.

  • Enhanced tracking prevention
  • Focus on accessibility
  • Trusted by millions of users
  • Strict tracking protection may break websites
  • May require heavy PC resources

Mozilla Firefox f eatures: Enhanced tracking protection | Firefox Focus for mobile | Strict privacy standards |   DNS queries sent to a secure resolver service | Focus on accessibility | Encrypted Client Hello

Firefox is a must-have for individual browser privacy across multiple devices. 

One of Firefox's most important privacy features is enhanced tracking protection. Mozilla has borrowed Tor techniques to block browser fingerprinting, and Firefox developers are constantly seeking to improve tracking-prevention features.

Firefox is rich with choices to customize the browser for privacy. It blocks social media trackers, cross-site tracking cookies, tracking in private windows, crypto miners, and fingerprinting scripts. There is a "strict" mode, too, that might break some sites when trackers are hidden in content -- but there are ways to allow enhanced tracking protection for trusted sites. Furthermore, a recent improvement is the introduction of Encrypted Client Hello (ECH).

Users enjoy Firefox's privacy focus but note that it can be a resource hog.

The other option for Firefox fans is Firefox Focus , a privacy-focused browser for iOS and Android that blocks trackers and has a built-in ad blocker.    

Mozilla also offers a VPN , with the option to connect up to five devices to over 500 servers in 30 countries.

The Tor browser

Best for anonymous browsing.

  • High levels of anonymity
  • DuckDuckGo integration
  • Constant updates and improvements
  • Learning curve to use
  • Can be slow

The Tor browser f eatures : Onion routing | DuckDuckGo integration | Access to websites outside of the clear web

Another great choice for improving your privacy on the web is the Tor browser, a non-profit project focused on anonymizing users online.

Its proprietary web browser disguises a user's IP address and activity by relaying it through a network of servers (nodes) run by volunteers. Bouncing your information around makes it exceptionally difficult to track, which is great if you don't want your ISP or anyone else spying on your online activity. 

Tor can be a crucial tool for whistleblowers, journalists, activists, and people avoiding censorship. The Tor browser is also a popular choice for accessing the deep web: A collection of websites and pages that are inaccessible through traditional means, like search engines, in what is known as the "clear" web. 

Also:  How to use Tor browser (and why you should)

The Tor browser's default search engine is DuckDuckGo, which will not log or store your search queries.

While it isn't a mainstream choice, the Tor browser is a well-regarded browser for people who don't want to be tracked across the web, and it gets updated frequently by  the Tor Project . Users applaud the network's tough approach to privacy but note slow speeds and occasional problems with Captchas.

Page loads in the Tor browser can be slower and some sites might not work well due to the architecture of the Tor network. Nonetheless, the Tor browser is a privacy-preserving browser worthy of consideration.

Best browser for private searches

  • Available across different operating systems
  • Solid commitment to user privacy
  • Email protection settings
  • Bland browser design

DuckDuckGo f eatures: Chrome and Firefox supported | Mobile and desktop private browser | Does not collect user data | AI experiments | No search engine query trackers

When it comes to DuckDuckGo, user privacy comes first. 

The privacy-focused search engine and browser is a vocal supporter of consumer privacy rights and now handles millions of user search queries daily.

There is a growing appetite for privacy-focused alternatives to tech giants like Facebook and Google. DuckDuckGo's Privacy Essentials extension for Chrome , Firefox , and Microsoft's Edge  has also proven popular. Its reputation is built on the idea that it does not collect user data but can provide the same search results as those that do. 

DuckDuckGo used to be a search engine rather than a full browser, but then released a mobile-friendly browser app and, now, a desktop version. The organization's browser provides a private search, website protection and blockers, web encryption, and more.

DuckDuckGo is experimenting with AI-assisted technologies to improve the search experience and has recently upgraded its browser . Users appreciate the firm's privacy focus, although some complain of censorship -- a concept DuckDuckGo staunchly denies . 

Mullvad Browser

Best for use with a vpn.

  • Two heavyweight privacy developers
  • Fingerprint, tracker blocks
  • Tor-based privacy features
  • New, so less thoroughly tested

Mullvad Browser f eatures : Fingerprint masking approach | Removes online identifiers | Private mode enabled by default | Blocks trackers, cookies

Mullvad is a relatively new entry to the secure browser market.

Not to be confused with the Tor browser, the Mullvad Browser is marketed as the "Tor Browser without the Tor network." The browser is built by the Tor Project team and distributed by Mullvad, a respected Swedish virtual private network provider. 

The idea behind the browser is to emulate the Tor network by creating a similar fingerprint for all users, improving anonymity. Furthermore, the browser comes with a private mode out of the box, tracking and cookies are blocked, and online functions used to extract information from visitors -- such as device identifiers -- are prevented.

You can use the browser as a standalone product, or you can combine it with Mullvad VPN . Users have given generally positive reviews, although you may find yourself signing up for the VPN for the best setup -- and it's not the cheapest on the market.

However, you should keep in mind that Mullvad was  subject to a search warrant by the National Operations Department (NOA) of the Swedish Police in 2023. Mullvad staff said that as the customer data did not exist, law enforcement was left with nothing (and no customer information). 

What is the best browser for privacy?

Brave is our top pick for the best browser for privacy based on its approach to user privacy, ad tracking prevention, the wide range of privacy settings on offer, usability, and speed. However, no browser is perfect, so you must decide which option suits you best.

Which is the right browser for privacy for you?

Not one size fits all, so be sure to reference the table below to better understand which browser suits your use case.

Factors to consider when choosing a secure browser

When you are switching to a more secure browser, there are some important factors to consider:

  • Online identifiers : You should check to see if the browser tracks any of your activities, visits, or search queries. This data can be used to create profiles for targeted advertising and may be used to track you across different websites.
  • Audits : The best secure browsers will conduct frequent security audits and have consistent patch releases to fix vulnerabilities and bugs that could expose users to risk. 
  • Speed vs. security : Some browsers will route your traffic through a number of servers to vastly reduce the likelihood of you being tracked. However, you will need to decide how slow you're willing the connections and browsing to be.
  • VPN : If you want to use a VPN, consider whether or not the browser works well with one -- or if the browser offers a built-in solution.

How did we choose these browsers for privacy?

While investigating the best browsers for privacy in 2024, we compared each of these browsers and extensions to determine what makes them different and which is best for different use cases. 

  • Balance : The balance between managing user privacy and funding a business can be a tricky one for companies to manage, but as we've shown, many developers are willing to wave the security flag on behalf of users over potential opportunities to generate more revenue.
  • User experience : We reviewed customer feedback to ensure that the majority of users find the browsers easy to install and use.
  • Features : We like to see additional privacy-enhancing features, like onion routing. We chose providers who offer more than standard browsing experiences. 
  • Platform support : We selected browsers offering a range of support for different operating systems and platforms, as well as mobile coverage. 

How does a privacy browser work?

A privacy browser works by automatically erasing your browsing and search history and cookies. It also may limit web tracking, and some even help hide your location (IP address). Privacy-focused browsers may also promote virtual private network (VPN) usage and may include features designed to bypass censorship blocks and keep users as anonymous as possible, such as access to onion routing and refusing to log site visits or web searches.

Do I need a privacy browser?

If you are concerned about your online privacy, you should install a privacy browser or at least an extension. We have to take responsibility for our own privacy online these days, and you can't rely on companies to do the job for you. 

Also:  How to delete yourself from internet search results and hide your identity online

We can recommend a few basic steps to take: Download one of the privacy-first browsers listed above that doesn't log your queries and activities, install a VPN, and use messaging apps with end-to-end encryption. 

Does using a private browsing window hide my IP address?

If you're using Chrome, an incognito window doesn't hide your IP address. It simply doesn't store your browser history, information you've entered into forms, or what permissions you've given to sites you've visited. Microsoft Edge, Firefox, and Opera all use a similar form of "anonymous" web window for browsing, but they aren't truly hiding your online identity. 

Also:   The best VPN services (and whether it's worth trying free VPNs)

If you want to block your IP address from being viewed or tracked, you can download a VPN , which masks your IP address so your service provider (or anyone else, for that matter) can't see what you're doing.

What is the most common personal web security risk?

Honestly? Putting your personal or contact information on social media. If you have your full name, phone number, address, or place of work anywhere on your social media, someone can use it to wreak havoc on your personal accounts. 

To prevent this, avoid using your real name online where possible, turn off location tracking, and don't post about your place of work if you can help it. All it takes is a single piece of personal information for someone with very bad intentions to get ahold of your entire online presence -- and so if you're posting photos of you away from home and on holiday, for example, you're letting people know your home is vulnerable.

Also:  The best security keys

Those innocent-looking name generator memes are another big issue; the ones that have you type out your first pet's name and your childhood street name (or something similar) to make up a gnome (or whatever) name. These are answers to common password recovery questions, so by letting the world know that your Christmas elf name is Fluffy Elm Street, you could be handing over all of your personal accounts to internet criminals. 

Are there other browsers worth considering?

Online privacy and security are hot topics today. The amount of data quietly collected on each and every one of us is staggering -- and beyond targeted advertisements, you may not realize it. 

The browsers we've recommended above can help tighten up your defenses against tracking and online monitoring, but as no browser is a perfect solution, you may also want to consider the alternatives below:

Apple details how superfast Safari upgrades help developers make web apps bigger and faster than ever before

Safari is now faster than ever.

Search in Safari on an iPhone

Apple might have finally agreed to allow things like game streaming apps into the App Store but there are still plenty of apps that are only available via web-based alternatives in Safari. Those apps need to be bigger and faster than ever before and making that possible means being at the forefront of web-based technology and performance. Safari has historically been pretty quick, especially on the iPhone, and now the team behind it has detailed some recent speed improvements.

Safari is based on the WebKit web browser engine and it's the WebKit team that has detailed some changes that have been made to the underlying technology to enable web developers to build the kinds of experiences that they wouldn't normally be able to do.

Specifically, the Apple WebKit team says that it has been able to improve performance by around 60% of late, although it did take multiple different updates to the Safari app over the course of months in order to make that happen. Regardless, the upshot is the same — Safari is now faster than ever, and that's good news for developers and users alike.

Faster than fast

According to the blog post on the WebKit website, the speed improvements were made thanks to the introduction of the Speedometer 3.0 benchmarking system which in turn allowed WebKit developers to get a better understanding of how its software performs.

Discussing the tool, the WebKit team said that "these tooling improvements allowed us to quickly identify bottlenecks" with those bottlenecks then giving the team something to aim for.

The blog post then continued to detail what Apple was able to do including building a "shared understanding of web performance so that improvements can be made to enhance the user experience."

So how successful was it? As it turns out, pretty successful. "With all these optimizations and dozens more, we were able to improve the overall Speedometer 3.0 score by ~60% between Safari 17.0 and Safari 17.4," the post explains. "Even though individual progressions were often less than 1%, over time, they all stacked up together to make a big difference." The post continued, adding that the team is " thrilled to deliver these performance improvements to our users allowing web developers to build websites and web apps that are more responsive and snappier than ever."

iMore offers spot-on advice and guidance from our team of experts, with decades of Apple device experience to lean on. Learn more with iMore!

It's important to note that the improvements to performance when using Speedometer 3.0 don't just mean a better score for those running the tests, but rather real-world improvements that users of web apps across the world — and across Apple's platforms — can expect to be of benefit when running real apps.

It's also worth noting that outside the EU, all web browsers available for download via the best iPhone and iPad App Stores use the same WebKit browser engine at their core. That should ensure that these speed improvements will also benefit those who use other browsers on their devices, no matter which company makes them.

8 Reasons Why Your Internet is Slow (and How to Fix It)

Expert tips to banish slow internet speeds

' src=

You can generally fix a slow internet connection if the issue is on your end, but the solution depends on what’s causing the slowdowns. Speed bottlenecks happen for a number of reasons: a slow internet plan, Wi-Fi interference, outdated or malfunctioning equipment, the list goes on. 

You can easily lose an afternoon troubleshooting internet issues, but we have a quicker way to get things back up to speed. We put together a list of the eight most common reasons for a slow internet connection; chances are, one of these fixes will solve your issue. Before resigning to a lengthy troubleshooting session or an expensive technician appointment, we recommend you run through the list and save yourself some hassle.

Why is your internet so slow?

We provide more detail on each of these potential internet slowdown causes further down the page. Click on an issue to auto-scroll to the solution.

Here are the most common reasons for a slow internet connection:

1. You need to restart your modem and router Equipment restarts are hands down the most effective internet troubleshooting solution. This should always be your first step.

2. Your home network is congested Congestion happens when you overload your internet connection with more traffic than it can handle. To fix it, you can either lower your internet usage or upgrade to a faster plan.

3. Your provider’s network is congested Provider networks can get overloaded the same way your home network can: too much traffic and not enough bandwidth.

4. You need a stronger Wi-Fi signal You experience a weak Wi-Fi signal when you’re too far from your router, when the signal is forced to pass through obstructive materials, or when other Wi-Fi networks and electronic devices introduce interference. You can fix it by extending your Wi-Fi range, choosing a better spot for your router, or adjusting your router’s settings.

5. You exceeded your data cap Many internet providers limit how much data you can use per month. When you go over your limit, your ISP may slow your connection. You can avoid exceeding your data cap by keeping track of your data usage or by purchasing more data.

6. You have high latency High latency causes your internet to feel sluggish and is particularly frustrating with highly time-sensitive activities like gaming and video calls.

7. You have slow or outdated devices It’s not always your internet connection that’s causing the slowdowns, it could be one or more of your devices. If your slowdowns are limited to certain devices, you should start your troubleshooting efforts with those devices rather than your internet connection; sometimes, they just need a simple restart.

8. Your provider is throttling your connection Your ISP may be intentionally slowing down your connection for a number of reasons.

How to fix a slow internet connection

1. you need to restart your modem and router.

As the golden rule of internet troubleshooting, an equipment restart should always be your first step. It’s quick, easy, and effective.

The restart process is the same for a modem, router, or gateway (modem/router combo unit):

Step 1: Unplug the power cable from the back of the modem, router, or gateway.

Step 2: Wait 60 seconds.

Step 3: Plug the power cable back into the back of the equipment.

Step 4: Wait for the equipment to reboot (this can take up to 20 minutes).

2. Your home network is congested

Your slow speeds might be the result of trying to do too much at once on your internet connection. Think of your internet connection as a road directly to your house. One car’s worth of people (or internet data) can reach your house at a time. If there are three cars trying to get there, they have to line up to get to your house. And if more cars arrive as the others are waiting to reach your house, you get a traffic jam.

Here’s how you can tell if you need to upgrade your internet plan:

Use our internet speed test to see if you’re getting the speed advertised by your ISP. If your results are close to your plan speed, consider upgrading.

You can also fix home network congestion by dialing back your internet usage. Thankfully, there are severa l easy ways to do this that don’t include yelling at everyone to get off the internet so you can attend a Zoom meeting.

Here are a few tips on how to manage your home network traffic:

Use QoS settings to prioritize certain online activities

Many routers have a quality of service (or QoS) component that allows you to prioritize certain types of traffic on your home network. For example, you can make sure your streaming data always gets first access to available bandwidth for smooth playback.

Not all routers have adjustable QoS, but if your router does, you’ll find the controls in your router’s web interface. If you need help accessing your router’s settings see our guide on how log into your router .

Prune your internet connections

There may be some devices connected to your network that you rarely use—if at all. Even if you’re not actively using these devices, it still uses bandwidth for updates and other background services. Your router may even have a limited number of devices it can connect to simultaneously, and start kicking some of them off the network when you go over the limit.  

One simple way to take stock of all the devices using your network is to load your router’s web interface and view the network map. You will see all connected devices, whether they’re active or not, so you can block the ones you never use. Some routers have an app you can use instead of a web interface.

Another method is to change the Wi-Fi password, but that only applies to wireless devices . Once you do , you must manually reconnect every device .

Stagger bandwidth-hogging activities

If your connection can’t handle everyone online at once, stagger your internet activities so everyone gets a chance at an uninterrupted connection.

Also, make sure to schedule big downloads (like computer and game updates) during times when other people won’t be online.

Put visitors on a guest network

You can create a second guest network using your router’s web interface or mobile app. A guest network allows you to limit how much bandwidth guests can use, and what services and websites they can access . It also provides improved security by preventing guests’ devices from mingling with your devices, so there’s no worry about guests spreading malware to everything you use. Our guide on how to set up guest Wi-Fi covers a few different ways to establish a second network.

3. Your provider’s network is congested

Your ISP is also susceptible to network congestion. It’s similar to congestion on your home network but on a larger scale.

If the congestion gets particularly bad, your internet provider may throttle internet speeds in your area to reduce traffic for the network.

Unfortunately, large-scale network congestion is out of your control, but you can try to work around it by s cheduling big downloads during non-peak hours, like in the middle of the night.

When dealing with heavy ISP slowdowns that don’t resolve, the only real fix is switch ISPs. Luckily, there are lots of new services available, like 5G home internet, Satellite, and new fiber developments. If you’re craving a shiny new ISP, run your zip code in the search bar below; chances are you have some new ISP options.

4. You need a stronger Wi-Fi signal

Walls, distance, and interference from other Wi-Fi networks can weaken your Wi-Fi signal. Weaker Wi-Fi signals mean slower speeds and frequent disconnects . 

You can tell if signal interference and weak Wi-Fi signals are your issue by looking at your devices Wi-Fi meter . For fast connection, we recommend ensuring you have at least three bars of signal strength.

To fix weak Wi-Fi, first, check your router’s placement. Y ou want to make sure your router is in a central and elevated location and away from things that can affect your Wi-Fi signals (like walls, Bluetooth speakers, etc.). Sometimes, even moving your router a few feet can make a big difference. See our guide on choosing the best spot for your router . We also have a walkthrough on how to move your router to another room , which may be required to get adequate Wi-Fi coverage throughout your home. 

If that doesn’t work, you might need to replace your router with one designed for longer ranges or better coverage—or you can add an extender to your network to stretch Wi-Fi signals into a previously unreachable area . 

Check out our guides on how to extend your Wi-Fi range and long-range routers if you need better Wi-Fi coverage.

5. You exceeded your data cap

Many internet providers have data caps, and some slow your speeds to a crawl once you exceed your plan’s data limit. You can usually check to see how much data you’ve used on your online account or through your ISP’s app. Providers like Xfinity give customers very high data caps—1.2 TB for this example—and shouldn’t cause too many issues for most households. 

Satellite internet providers charge for internet use by data rather than by internet speed. It’s similar to how cell phone plans usually work: once you use up your data allowance for the month , your internet speeds are throttled. 

Hughesnet customers can see speeds drop to 1–3 Mbps. Viasat customers can expect all their internet traffic to be deprioritized, meaning that their data gets pushed to the back of the line of all Viasat customers’ data.

Many DSL, cable, and fiber internet companies are discontinuing data limits , but there are many others that continue to keep them in place . Look to see if your internet service has a data cap in our guide to ISP data caps .

6. You have high latency

Latency is the time data takes to make a round trip from your device to the destination and back. A high latency creates noticeable lag: an extended duration between your physical actions and the results displayed on your screen. This can be particularly frustrating with online gaming or video calls. 

High latency is difficult to work around. It depends partially on your physical distance from internet servers, network congestion between you and the servers , and your internet provider’s infrastructure—things that are mostly beyond your control. Internet type can also play into latency as well. 

For example, satellite internet has high latency because all your data must travel to space and back, both coming and going to your device. Newer types of internet, including fiber and 5G mmWave , have lower latency because they can handle faster signals. 

If you’re looking to lower your latency for a better connection, check out our report on the fastest ISPs . It dives into which internet services have the best tested speeds and lowest average latency.

7. You have slow or outdated devices

The problem might not be with your internet connection—it might be with the device you use . Your computer, tablet, phone, or gaming console could be outdated and not capable of processing today’s Wi-Fi speeds.

For example, the old (but much loved) PlayStation Vita handheld console supports up to 150 Mbps per second because it uses a Wi-Fi 4 radio. That speed can decrease based on the router it connects to and the security protocol it uses. The Vita will never see speeds beyond that 150 Mbps limit.

If you have speed issues on a desktop or laptop, try power cycling the device. This clears the memory of any junk, refreshes your connection, and cleans out unnecessary processes and temporary files. Speed issues tend to happen due to an overworked processor, and a quick power cycle—shutting it down completely for 30 seconds—will “clear its head.”

Other things that can slow down your devices include the following:

  • Too many open applications
  • Too many open browser tabs
  • Outdated software
  • Outdated drivers
  • The operating system needs to reboot to install updates
  • Patch downloads
  • App downloads

Avoid overwhelming your computer’s CPU by closing unused applications and browser windows. Keep your device’s operating system up to date by allowing auto-updates, and keep your antivirus definitions current.

8. ISP throttling

Internet providers can throttle your speeds, causing a slow connection . We’ll go over throttling briefly here, but you can get a more in-depth look at the subject in our guide to network throttling .

We’ve already discussed a few circumstances where a provider might throttle your speeds—like if you go over your data cap or if there’s too much congestion in the network. But your provider might also slow you down if it flags your internet activity as potentially illegal or if it generally doesn’t want you to do a specific type of activity (like torrenting). 

To see if your provider is throttling your internet, run a speed test normally and then run it again using a VPN. If your speeds improve with the VPN, congratulations! You’re throttled.

Other factors that affect your speed

Your internet plan’s maximum speed.

Internet speeds are measured in megabits per second (Mbps) . This refers to your connection’s total bandwidth, not the actual time data uses to make a round trip to a website and back—that’s called latency.

Providers usually advertise their internet speeds as “up to” a certain number of megabits per second, and there’s usually some fine print that says those speeds are not guaranteed. Internet providers are mostly in the clear legally if your internet doesn’t actually perform up to the highest advertised bandwidth.

Realistically, you may pay for 400 Mbps per month, but you may not see that maximum due to hardware issues between your internet provider’s operator—a device that communicates with multiple modems—and your physical internet connection. Utility pole connections, your buried cable, and so on all play a major factor in how your connection performs.

If you need a refresher on internet speeds and what they mean, check out our guide to internet speeds .

Your upload and download speeds

You upload and download data every day, whether you’re on a smartphone or a laptop. For instance, when you access a website, you upload a request to that website and then download temporary files from the site to view it in your browser.

If you don’t have issues with streaming on Netflix or downloading files but are still experiencing some symptoms of slow internet speeds, your issue might actually be with your upload speed.

Cable, DSL, and satellite providers give customers way less upload bandwidth than download bandwidth because most people request much more information from the internet than they send. Upload speed is typically an issue for heavy uploaders—like Twitch streamers , people who work with video or audio , or those who often have to share large files. 

The best way to improve upload speeds is to switch to a fiber plan. Fiber-optic internet connections often give customers upload speeds equal to their download speeds. If you don’t know what kind of speeds you really need , check out our recommendations for upload and download speeds .

Your internet connection type

There are a few different technologies internet providers use to deliver your connection, like cable, fiber, satellite, or DSL. Your internet connection type p lays a huge factor in your overall speeds.

Satellite internet transfers internet signals from a base station to a satellite to a receiver at your home. Because all your information must travel such a long distance both ways, satellite internet can have very high latency compared to other types of internet, which slows things down. 

DSL internet uses phone lines to carry data. It can’t handle the same amount of bandwidth as cable or fiber. DSL internet tops out at just over 100 Mbps, and its electrical signals tend to degrade in quality over long distances. 

Cable internet is faster than DSL because it uses coaxial cables that have a higher bandwidth than phone cables . Speeds can reach up to 1,200 Mbps.

Fiber-optic internet is one of the newest types of internet, and it’s the best wired connection you can get. Fiber uses light pulses to send your internet data, so it has lower latency than other internet types as a whole. It can also carry much more bandwidth than cable or DSL, offering speeds up to 5 ,000 Mbps. It’s less prone to network congestion and offers equally high download and upload speeds.

Overall, DSL and cable are the most common internet types while fiber is newer but scarce. Satellite is best for rural areas where the other three types can’t reach.

More ways to speed up a slow internet connection

We provide some quick tips below to help speed up your internet connection. But if you’re ready to get to the bottom of your internet speed issues with some thorough troubleshooting, see our internet troubleshooting guide .

First, know your plan speed

You need to know how much speed you pay for each month and compare that number against the speed you’re actually getting now . Look on your paper bill or log in to your online account to see your plan’s advertised maximum speed.

Next, run a speed test and compare

Running a series of speed tests while connected to different points in your network can help you figure out where your speeds are slowing down. We’ll break the testing process down into two sections.

Part 1: Test the modem

Your first speed test is to see if you’re getting the correct speeds to your home compared with what you’re supposed to get from your internet provider . To get the most accurate results for your initial speed test, unplug your router from the modem and connect a computer to the same port on the modem using an Ethernet cable. If you have a wireless gateway, just plug it into one of the Ethernet ports.

Warning: We don’t recommend browsing the internet for extended periods of time without using a router. Your router has some excellent built-in security features that protect your network from viruses and malware.

This first test should give you results that are close to the speeds promoted with your plan. If not, try to track this issue over multiple days and times of day to establish a pattern. Contact your internet provider to talk about why you’re not getting the correct speeds if you continue to see lower than expected results .

Part 2: Test the router

If your modem isn’t the issue, the next step is to test the router. Plug the router back into the modem and run multiple speed tests using your wireless devices, and wired devices plugged into the router’s Ethernet ports.

If you see a vast difference between the modem and router tests, then your router is causing your connection slowdowns—or the Ethernet cable tethering your router to the modem.

Keep in mind that not all wireless devices experience identical speeds. Their connections depend on the hardware inside no matter what router you use, so a budget Samsung phone will have slower Wi-Fi speeds than an expensive wireless card plugged into your desktop.

To troubleshoot router problems, follow these steps:

Step 1: Unplug the router’s power , wait 30 seconds, and then plug it back in.

Step 2: Make sure all cables are connected securely and that all ports work.

Step 3: Update your router’s firmware. You can do this by logging in to your router’s web interface or mobile app . (Your ISP likely does this automatically, but it’s worth checking.)

Step 4: Reposition your router .

Step 5: Move wireless connections to the best Wi-Fi band .

Step 6: Change Wi-Fi channels in your router’s interface to find one that’s less crowded.

Step 7: Try a factory reset by pressing the reset button located on the back of your router.

If none of these steps work, you may need to upgrade to a newer or more powerful router. Internet tech advances rather quickly, and if your router is more than a few years old, it might be time to get yourself something more modern .  If you’re looking for router-buying guidance, we have recommendations for the best long-range routers , the best modem and router combos , and the best routers for Xfinity .

Check for Wi-Fi dead zones

Wi-Fi problems can stem from multiple factors . It could be your router’s range, a crowded frequency channel or band, or signal interference caused by physical obstructions and other electronics. 

You already know that you should place your router at a central and elevated location for the best coverage, so we’ll assume that you’ve already done that and pointed your antennas in the right direction.

Go to different areas of your house with a computer or smartphone and watch the Wi-Fi signal strength indicator. If you notice a lot of dead zones, you may need to move your router again (if they happen in areas where you normally need Wi-Fi) or invest in something to boost your Wi-Fi signal to that particular area. You can also make a Wi-Fi heatmap if you want to get more precise with it. 

If you have more than a couple of issues with Wi-Fi dead zones, we recommend upgrading to a mesh networking kit . They usually ship with at least two nodes—one that connects to your modem and another that communicates directly with the first unit—to create a ”blanket” of coverage. There’s no centralized point, and you can easily add more nodes to extend coverage. Moreover, devices seamlessly switch between nodes as you move about the home or office.

If you prefer to stick with the traditional router, you could add a Wi-Fi extender or powerline adapter , However, we still prefer mesh router kits versus the router/extender setup .

Reorganize your Wi-Fi connections

If you’ve already pruned your Wi-Fi connections of unnecessary devices , it’s time to make sure all active connections are on the correct Wi-Fi band. 

Most modern routers offer two Wi-Fi bands, which each create their own visible Wi-Fi network. By default, these are usually labeled with their frequency bands, but it might be different if you’ve changed your Wi-Fi network’s name. 

These bands operate on two different frequencies: 2.4 GHz and 5 GHz. The 2.4 GHz frequency band has a better range, but it’s slower and more susceptible to signal interference from other electronics. The 5 GHz band is faster but can’t travel as far. 

Basically, you want to use the 5 GHz band for most bandwidth-heavy applications like streaming or gaming. Devices that don’t need that much speed—like smart home devices— should use the 2.4 GHz band instead .

Typically, you can change the Wi-Fi band each device uses by logging in to the correct Wi-Fi network on each device. However, some routers broadcast only one network name and automatically selects the best frequency band for your device. This can be problematic if you really need the faster 5 GHz connection, but the router forces your device to use the 2.4 GHz band.

Change your Wi-Fi band’s channel

Changing your router’s channel is a standard troubleshooting suggestion, but it may not work, and here’s why.

All three frequency bands are divided into small 20 MHz channels, and routers combine these channels to make larger ones. Most modern Wi-Fi 5 and Wi-Fi 6 devices use 80 MHz channels when they connect to the 5 GHz band for the most speed, so routers use these by default.

The thing is, routers only list the smaller channels, so you may run a Wi-Fi diagnostics app and see that channel 36 is clear for you to use, but in reality, it’s probably being used by a neighboring network that, like yours, combines channels 36, 40, 44, and 48 to create one 80 MHz channel.

If that’s the case, your best bet is to select one of the higher 5 GHz channels (if they’re available to you) and hope for the best. Most standalone routers allow you to change the channel in the web interface or mobile app, but you usually can’t change the channel on a mesh system.

Check connected devices

As we mentioned before, sometimes the issue isn’t with your internet connection— it’s with the smartphone, computer, or tablet you’re using to access the internet . It may need a reboot, it may be outdated, or you have too many apps and programs open, bogging down the device’s processor.

Manage your network

If you’ve made it this far and you’re still experiencing problems with slow internet speeds, run through the tips in the home network traffic section of this post if you haven’t already. 

Your speed issues most likely stem from your internet provider’s reliability or the traffic on your own home network. Even if you’ve organized and trimmed down your number of connected devices, you could still not have enough bandwidth at certain times of day to cover everything your network has to handle. The only solution to this is to either use the internet less or get a faster internet plan.

Check out every provider and plan in your area to see if you can get better speeds for a better deal.

Quick fixes for slow internet speeds (and why they work)

Before we dive in, download our internet speed test. Measuring your internet speed and knowing how it compares to the speeds you pay for is an important part of diagnosing a slow connection.

Fix #1: Power cycle your modem and router (or wireless gateway)

Your modem and router work hard , and sometimes they need to refresh with a quick power cycle. Simply pull the plug on both units, wait 30 seconds, and then plug the modem back into the wall outlet. Once it properly boots, do the same with the router.

In the case of a wireless gateway, pull the plug, wait, and plug it back in.

Draining both units of power allows them to clear the system memory, clear up any local communication issues, and reestablish fresh connections. Moreover, a power cycle allows the modem to resync with your internet provider’s operator—a device that communicates with multiple modems. It also refreshes your router’s public IP address.

Overall, a power cycle can really give your internet speeds a boost on your side of the modem.

Fix #2: Move your router to another location

Many people hide their routers or wireless gateways in closets, behind furniture , or down in basement s . Don’t be one of those people unless you want excessively bad Wi-Fi.

Instead , put as few physical barriers between your router and your devices as possible. Walls, floors, ceilings , doors, large furniture, and similar obstructions can barricade your Wi-Fi signals and reduce connection speeds , especially over longer distances. 

Certain signals from other devices can also interfere with your wireless speeds. These include microwaves, Bluetooth speakers, baby monitors, and cordless phones.

For the best Wi-Fi coverage, place your router in a central, elevated location, or at a location where you use Wi-Fi the most, like in a home office .

Be sure to use your router’s external antennas ( if present ) to get better Wi-Fi coverage. Most router antennas broadcast Wi-Fi signals in an outward circle perpendicular to the antenna’s position . For instance, if the antennas are positioned vertically, the Wi-Fi signals broadcast horizontally in all directions.

That said, if you live in a one-story house, keep the antennas vertical. If you live in a multistory house, position at least one antenna horizontally so the Wi-Fi signals reach the additional floors.

Fix #3: Use the internet during off-peak hours

If you know there’s a big download in your future— the latest version of macOS or a 100 GB update for an Xbox Series X game—you might want to schedule a time when you don’t need to do anything else online. The early morning hours are ideal when everyone is asleep and no other downloads currently hog your bandwidth.

Operating systems tend to wait until the early morning hours when you’re fast asleep. Game updates, meanwhile, typically require you to manually start the download. Other updates aren’t quite so accommodating with your schedule.

If your internet gets too slow to stream during certain peak hours, download the content earlier in the day (or again, in the middle of the night) so you’ll be ready to binge watch all of Avatar: The Last Airbender without buffering -related interruptions.

Fix #4: Upgrade your internet plan

You may need a faster plan if more people live with you now, if you transitioned to working from home, or if you generally use the internet more than you did before. Enter your zip code below to find a speedier plan that’s available in your area .

How do I know if I need a faster internet plan?

What is type of internet plan is the fastest.

Fiber internet is the fastest type of internet connection you can get. Many residential fiber-optic internet plans offer speeds up to 5,000 Mbps. There are even some fiber plans that offer 10,000 Mbps of bandwidth. Additionally, fiber internet offers symmetrical speeds, meaning your upload speeds are just as fast as your download speeds—a handy feature for activities like zoom calls, twitch streaming, and uploading large files.

Major mail delivery delays raise concerns about voting in the 2024 elections

U.S. Postal Service trucks

In Virginia, hundreds of veterans had their colon cancer screening tests invalidated after the results took months to arrive by mail. An Atlanta college student missed an academic trip to Ghana when their passport with two-day shipping took a month to show up. A bride in Texas had to rent a dress for her wedding after hers spent weeks stuck in a Houston postal facility.

Across the country, residents and businesses have been reporting widespread slowdowns in mail and package delivery by the U.S. Postal Service. The delays have become so persistent that members of Congress have gotten involved, urging the Postal Service to drastically correct course and raising concern about what impact the disruptions could have on mail-in ballots in the upcoming election.

The delays appear to largely stem from a new system the Postal Service began rolling out last fall that will eventually funnel all the nation’s letters and packages through a consolidated network of 60 regional distribution centers — similar to the airlines’ hub-and-spoke model. The change is part of a wider $40 billion, 10-year overhaul of the network that Postmaster General Louis DeJoy has said will reduce costs, improve reliability and make the Postal Service more competitive. But in some instances, the plan has done the opposite, according to the Office of the Inspector General for the Postal Service, members of Congress and Postal Service advocacy groups.

“It’s just a dumpster fire right now,” said Leo Raymond, a former Postal Service manager and managing director of Mailers Hub, an industry group for direct mail companies. He said his members have had everything from customer bills to strategically timed marketing material caught up in the delays. “If you’re a business, you’re going to be discouraged from using the mail because you want your stuff to actually get there.”

Nationwide, 87% of first class, two-day mail arrived on time during the last three months of 2023, a 2.5 percentage-point decrease from the same period a year earlier, according to data published by the Postal Service inspector general. For mail intended to take three to five days, just 70% arrived on time, a decrease of 11 percentage points, the data showed.

A top senator with oversight of the Postal Service, Gary Peters, called on the agency last month to pause any further changes to its distribution network over fears the delays could worsen and spread. But an official with Peters’ office said there has been no indication the Postal Service plans to do so.

“The nature of USPS’s network changes has now raised significant concerns including the potential for degraded rural service due to fewer facilities, delayed delivery of election mail that would be processed at out-of-state facilities, and critical health information such as laboratory tests not being processed same-day due to decreased transportation trips,” said Peters, a Michigan Democrat, in a March letter to DeJoy.

Delays have been the most significant in some of the first regions to roll out the new regional distribution system, including Richmond, Virginia, Houston and the metro Atlanta area.

Mail delays have become so prevalent in Richmond, which implemented one of the first regional distribution centers in October, that Richmond General Registrar Keith Balmer told residents in February not to send their ballots for the March presidential primary by mail and to instead use one of three drop boxes in the city or to vote in person at an early voting location or a polling site on Election Day. For the upcoming election, Balmer said he will be strongly urging voters to use drop boxes.

“I understand that these issues extend beyond mere inconvenience; they represent a fundamental threat to our democracy,” Balmer said in a blog post on Feb. 26.

The Postal Service has attributed the issues it has had over the past six months in Atlanta, Houston, Kansas City and Richmond to a range of factors, including a weather-related roof collapse, the transition to new processing equipment, the loss of a transportation vendor and “executional complications arising from operational transitions,” the Postal Service said in a statement to NBC News. But it said the disruptions have been improving.

“We readily acknowledge and regret that there have been service performance issues in several major metropolitan areas in the past six months,” the statement said. “In each of these site-specific disruptions, we have moved quickly to understand the local issue and stabilize the situation. As a result, service performance is improving or has returned to expected performance in these local communities.”

For the November election, the Postal Service said in its statement that it will “employ a robust and proven process to ensure proper handling and delivery of all Election Mail, including ballots.” During the November 2022 midterm elections, 98.96% of ballots sent by voters to election officials were delivered within three days, 99.82% were delivered within five days, and 99.93% were delivered within seven days, according to the Postal Service.

While the Postal Service said it is working to correct the issues that have occurred over the past several months, a report released this month by the inspector general for the Postal Service highlighted the complexities of the problems in Richmond.

The Postal Service had spent $25 million converting an existing facility near Richmond into one that would serve as a central hub for mail traveling from more than 100 miles away in Rocky Mount, North Carolina. As the new system rolled out, residents in Richmond began reporting significant disruptions to their mail starting in October. In the final three months of 2023, just 66% of mail there arrived on time, the worst rate in the country, according to data from the inspector general.

The report detailed poorly supervised staff, including workers idly waiting for the mail to arrive and one mail handler sleeping on a parked forklift, along with sloppy handling of the mail, including packages scattered around the facility floor, pieces of mail that had fallen under equipment, and 2-month-old mail found sitting in a container in the truck yard.

Poorly planned vehicle routes, which were being constantly changed, also added to delays, with a lack of drivers and vehicles sitting idle while they waited for mail to be sorted. Some trucks left with just a small fraction of the mail they could carry. As a result, the number of extra trips to the facility increased eightfold and late trips were up by 30%, according to the report.

While the Postal Service had estimated the new facility would reduce costs by $14 million in 2024, the facility paid out an extra $5 million in unauthorized overtime in 2023 and had $3 million in questionable transportation costs, the report said.

Among the pieces of mail caught up in the delays where colon cancer screening results for veterans. The Richmond Veterans Affairs Medical Center told members of Congress in late January that 870 at-home colon cancer tests used to indicate whether a patient needs further screening took so long to arrive that they were invalid, with some tests taking months to be delivered.

A spokesman for the VA said the delivery of tests has improved since local congressional leaders raised the issue with Postal Service officials earlier this year, but the medical center is exploring other options for delivering the tests in case there are future problems.

Hundreds of thousands of dollars in donations to the Virginia Museum of History and Culture in Richmond were also snarled up in the delays, said museum President Jamie Bosket. He said the museum saw a drop-off in the number of donations it was receiving by mail in October, just as it normally would see a surge in year-end contributions. By December, the museum had received just 10 pieces of mail from donors compared to the hundreds it would normally get in that month.

“We were missing at least 600 pieces of mail that represented at least a quarter of a million dollars in donations,” said Bosket. “For us, when there’s a disruption to memberships and charitable giving it’s a disruption to every element of our operation.”

Then in late January, bundles of mail began showing up with hundreds of donations, many of them postmarked in October, he said. Bosket said he believes most of the mail from 2023 has been delivered, but the museum’s mail remains sporadic.

“Something is wrong,” said Bosket. “We don’t know what it is and we don’t know how to find relief long term or have any reassurance that we can reliably use the Postal Service.”

In Atlanta, residents have experienced similar delays since a new regional distribution center opened there in late February. After the facility opened, on-time delivery service in the region went from 60%-70%, which was already below average, to as low as 20%, according to Raymond. Local news organizations reported on hundreds of complaints from residents and long lines of trucks backed up at the facility waiting to drop off and pick up mail.

“Atlanta has been a complete house on fire,” said Raymond.

The HBCU Green Fund, which organizes an annual trip to Africa for students at historically Black colleges and universities, said it had nine passports stuck in the mail in Atlanta for more than a month before a trip to Ghana. The group had to scramble to get new passports and visas issued for the students less than 48 hours before they were scheduled to depart last month, but one student was unable to get a new passport and had to miss the trip.

In Houston, the delays began in December following the opening of a new regional distribution center there. During a January press conference by Rep. Al Green, a Texas Democrat, one bride said her $1,600 dress didn’t arrive in time for her wedding and she had to rent one at the last minute. Irene Ramirez said her 89-year-old father’s heart medication from the VA spent more than 18 days stuck in the mail in Houston. She said she even tried calling the White House to get help after spending hours on the phone with the Postal Service, only to be repeatedly disconnected.

“I understand we are all fallible humans,” Ramirez said. “But when the failures are ongoing and administrative and put people’s lives at risk, I feel we need to stop and quickly reverse course.”

Rep. Sylvia Garcia, a Democrat who represents portions of the Houston area, said the delays seem to have improved and she didn’t hear of any significant mail-in ballot issues during the March presidential primary. But she remains concerned about the upcoming November election.

“We’re approaching a major November election,” Garcia said during a call with reporters last month. “We need to make sure that we iron out any difficulties, any obstacles, any barriers, any issues now, so that we don’t end up in a situation much like we were in with the November ballots.”

In prior elections, the Postal Service has used special procedures to ensure mail-in ballots are promptly delivered. But any disruptions near the election, even relatively isolated ones, could have wide-ranging implications.

“Hopefully this won’t turn into a problem,” said Steve Hutkins, who runs the website Save the Post Office. “But if the election is really close and a couple of key states have mail ballot issues, it could be a nightmare.”
