Firefox is a decent browser but when you open some sites like YouTube and notice your browser slowing down, lagging or freezing frequently, you need to address it.

For the most part, you probably have too many media browser tabs open or too many programs running in the background.

It is also possible that there are some problematic browser extensions or some settings that have been recently configured that conflict with the normal functioning of your Firefox browser.

How do I stop YouTube from slowing down Firefox?

1. Update and restart your browser

1.0 End browser processes

1.1 Check for browser updates

2. Clear the Cache and Cookies

3. Disable extensions

Extensions generally slow down your browserbut AdBlockers are the most notorious especially since YouTube started flagging them off. Disable all your ad extensions, restart your browser and see whether YouTube is still slowing down your Firefox browser.

4. Disable hardware acceleration

If you’re running a lot of GPU-intensive tasks, they may be competing for the limited resources hence why opening a YouTube tab on your Firefox browser causes a slowdown. And if your GPU is unable to handle all these tasks, your CPU usage will be high causing performance issues.

5. Adjust video settings

6. Reset Firefox

7. Open Firefox in troubleshoot mode

Firefox’s troubleshooting mode serves the same purpose as Windows Safe Mode. It runs the browser without the extensions to isolate the issue. If your Firefox browser’s speed improves, you can conclude your extensions are slowing down your browser.

8. Uninstall and reinstall Firefox

Alternatively, you canroll back to a previous Firefox versionor try another browser likeOpera GXto see if it’s a YouTube or browser-related issue.

Firefox may have its own issues where it slows downbecause of a bug but YouTube also tends to perform better on some browsers so you can pick one of theYouTube-recommended browsersfor an optimized experience.
