Firefox is unbelievably slow when I'm watching youtube videos

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)

@Yoru system specs? What add-ons are installed? What video res, 720, 1080, 4k?
- recently upgraded to an rx 6600 on a ryzen 5 5600 also 16 gigs of mem. here are the addons: the video res is 1080p
  
  Note that Dark Reader is insanely resource intensive.
  
  (Also note that Disconnect has been unmaintained since before the pandemic and is redundant because UO exists.)
  
  I use one called "Dark Background and Light Text" and only apply it to sites where I really need it.
  
  @Yoru Try clicking the gear in the menu bar, and turning off Ambient Mode. That lagged the crap out of my machine, but on a Intel iGPU.
  
  The dark themes in Enhancer for Youtube also disable ambient mode.
