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 always run with hardware acceleration off on all my Firefox machines, it seems to cause a lot of issues and the videos play just fine without it.
Depends on the setup. Disabling it on mine turns Firefox into a slideshow.
