Saw this ghacks article for speeding up YouTube on FF and seems to help. (www.ghacks.net)

I have seen folks talk about a pain point for using FF (or forks) being related to YouTube being super slow. The about:config settings the article mentions did seem to lead to YouTube loading faster on both my FF and Zen-Browser installs. So maybe this might help for others that specifically don't like to use FF as their main browser because of YouTube.

For those that just want the settings:

gfx.webrender.compositor.force-enabled (set to true and restart FF)

If on AMD GPU, this extra setting is supposed to help reduce CPU usage:

media.wmf.zero-copy-nv12-textures-force-enabled (set to true and restart FF)

Just tried it, setting gfx.webrender.compositor.force-enabled to true made firefox unusable with all sorts of visual glitches so I changed back both.

Kinda annoying. Somewhere a month ago firefox suddenly turned sluggish. It loads fine, video playback is ok as well, but the UI animations on the video player like seeking, changing volume, subtitles or video speed are really laggy.

I switched to a completely new profile and tried disabling all of my extensions but it's the same. Kinda accepted it at this point and am ignoring it. It came out of the blue hopefully it gets fixed as well.

YouTube recently introduced UI changes. Google probably didn't optimize for Firefox besides Chrome. Whatever they're doing, it may be more performance on Chrome than on Firefox for technical reasons.

You could try troubleshoot mode, or the other steps down this guide. It's similar to what you already did, but maybe it can help you catch something
