Key notes

Firefox is one of the most popular browsers on all platforms, but despite its massive popularity, it still has specific issues on Windows 10 and 11. Believe it or not, Firefox can be slow even this year.

Many users complain that Firefox is lagging on their devices, which can be a significant problem if you useitas a default browser.

Before going through these solutions, you may consider using a different browser that is even lighter than Firefox, and we recommend Opera GX.

The browser has built-in CPU, and RAM limiter features to improve response rates even more. They are easy to enable/disable in just one click and contribute a ton to performance.

The browser won’t use resources to load ads if you enable the built-in adblocker. The transition should be seamless because Opera GX has a modern, intuitive UI with familiar controls.

Opera GX

1. Change your power settings to High Performance

We must mention that switching to a High-Performance mode will drain your battery faster due to increased power consumption, but Firefox should be working without any slowdowns.Moreover, an even moreperformance-focused modethat you can enter in Windows 10 will allow you to use your PC in peak conditions.

2. Check if Firefox is up to date

If Firefox is slow on your PC, the problem might be a particular bug. To avoid Firefox bugs, it’s advised to update your Firefox to the latest version.

In most cases, Firefox will perform the update automatically, but you can always check for updates manually from Firefox.

3. Switch to a different theme

This is a potential workaround, but a few users reported that it works for them, so you might want to try it.

4. Change the accesibility.force feature

After enabling this option, check if the problem with Firefox is resolved.

5. Check your antivirus

You can try to disable your antivirus while browsing on Firefox, but that will expose you to online threats.

Alternatively, you might have to uninstall your antivirus to fix the problem. For example, many users reported issues with Norton antivirus.

We encourage you to check out our guide onremoving Norton Antivirusto ensure it’s completely removed.

6. Clear your browsing data

If you’re looking for a browser with great functionality that won’t slow down your PC, you might want to tryOpera One.

7. Disable add-ons

Some add-ons can cause specific websites likeYouTube to slow down your Firefox browserbecause of compatibility issues. It can be pretty frustrating when Firefox is running slow on Windows 10 or 11, but hopefully, some of our solutions might be helpful to you.

After all, Firefox is a great web browser, but sometimes you can experience slowdowns while using it. If you’re having more problems, you should check out ourFirefox issues guideto see how to fix them.
