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 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.
i have over a dozen addons in firefox, several user scripts (including ones that run on yt). i never log in.
i can q-up a days-long playlist and it'll just go and go. no problems.
Can you also watch twitch at 1080p without lag? Maybe you don't watch it, but I always had problems with that. Chrome works perfectly on twitch but not Firefox
Firefox plays 1080p twitch streams just fine for me on several machines.
i can watch 1080p content just fine on my geriatric pc (1st gen lynnfield), and even do h264 encoding in realtime or faster (sw ffmpeg), but discord and twitch just flat-out suck on it.
Hmmm, maybe my PC just sucks :'/
It could be many things.
Do you have a lot of extensions enabled?
Is your Firefox updated?
Is xmp or docp enabled so your ram is running at the right speeds?
Is hardware acceleration enabled/disabled in firefox?
Have you tried a fresh firefox profile/install? you could try downloading a beta/dev version and testing with that.
I have like 9 extensions, Firefox is always updated. I don't know but I have 8gb ddr2 ram (10 year old PC), I don't think I enabled hardware acceleration. I have not tried a new install.
I watch twitch at 1080p and YouTube at 4K with Firefox on Windows and Linux (same PC) without issue.
