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)

I watch twitch at 1080p and YouTube at 4K with Firefox on Windows and Linux (same PC) without issue.
