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)
Try frontend alternatives like piped or invidious
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 :/
Does the same happen on a clean profile? (you can create a new one in about:profiles)
On my machine it doesn’t even run properly after fresh installation and new profile and not one single page opened.
