Firefox Community Forum

Firefox just keeps getting slower and less responsive. I've cleared the history etc and run my Avast cleanup premium which helped a little, but the other browsers just put it to shame. I hate to switch because I love the user interface, but............ its just frustrating. Windows 11 latest updates.

I have a new desktop i7 computer with 16 GB of RAM. Why are my Firefox browser screens locking up? I'm running Windows 11 Pro. I don't have this problem with Chrome.

I used to play World of Tank and look at YouTube on my second screen. Everything went smooth untill this week. YouTube on Firefox on my second screen is lagging or freezing. I tried Opera, I tried Edge it worked fine, but with Firefox, it is no more possible to play YouTube on my second screen while playing. It is not a matter of graphic hardware as this issue only happen with Firefox. I tried to deactivate every module and to reinstall Firefox (either the Beta version) but still got the same lagging and freeze on YouTube. Do you need anything that can help you to investigate this issue, this is really terribly frustrating and boring.
