Firefox is unbelievably slow when I'm watching youtube videos
I have about 25 extensions (almost all needed) and firefox lags like crazy, it's like I'm watching the videos at 10 fps. I download chrome to test it out and sure enough it runs as smooth as butter. Any help?
EDIT: It somehow fixed itself after I started using LibreWolf (with the same addons)
I'd start by disabling all add-ons and check if that helps. If not, there's something wrong with Firefox itself.
If disabling them fixed the issue, I'd continue with a binary search to see if there's a specific addon causing issues. I.e. enable only half the add-ons and re-check. Then continue enabling/disabling add-ons until you know which addon causes the issue.
That said, it could be the combined load, or a combination of add-ons, which is significantly harder to fix.
Could be any number of things. Possibly a bad plug in or combination of plug-ins. Could be your new video card didn't jive with your installation of Firefox.
Run Firefox in safe mode and see if the performance improves. If it does, you likely have a plugin causing the issue. From there, disable all of them and reenable them one at a time to see if the problem comes back.
I found youtube videos unbearable as well and I found the culprit to be ambient mode in the video settings. I ended up adding a rule in ublock origin to delete the ambient mode stuff regardless of the setting just to make sure ambient mode is disabled in private windows etc.
the thing is it was running perfectly fine with 40+ addons, I guess it has smth to do with my new gpu? I'm outside rn I'll try the things the people recommend
I don't think this is a firefox-specific problem. I use FF on mac and PC and I've never had any issue with youtube. I have an m1 macbook air and a PC with a 4690k and a 1080, so lower spec than yours. 25 extensions running probably doesn't help, but it isn't just "firefox is slow".
unfortunately youtube isn't the only culprit. Firefox just seems laggy in general, the affect is multiplied in youtube
and indivious doesn't 1080p or 60 fps :/
I only have four or five extensions and YouTube videos lag. It's Firefox. I'll still not switch to anything else, but I could imagine a clean Chrome without anything added and zero bookmarks purely as video platform.
