Firefox is unbelievably slow when I'm watching youtube videos (lemmy.ml)

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)

As they said start disabling every add-on. If this doesn't solve it, it may be an issue with hardware acceleration. I remember some installations where Firefox wouldn't decode video on the graphics card by default. Do a duckduckgo 'hardware acceleration \ Firefox' and see if it works.

Edit: Also codecs, maybe something with the h265 codecs
