Firefox is unbelievably slow when I'm watching youtube videos

Yoru@lemmy.ml to Firefox@lemmy.ml – 41 points –

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.)

@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.
