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)
Firefox plays 1080p twitch streams just fine for me on several machines.
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 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.
