These two tweaks should improve Firefox's performance on YouTube significantly - gHacks Tech News

Here are two quick tweaks for improving the performance of the Firefox web browser on YouTube.

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)

*edit - per Zak in the comments. The AMD setting is Windows specific.

    Word of warning, I did this (gfx.webrender.compositor.force-enabled) on my Tuxedo OS system with Nvidia and I don’t know if it was just the next time I started Firefox or because said restart was after a big system update, but Firefox crashed on launch every time until managed to get it into safe mode (wasn’t as easy as holding shift) and then turned this back off.
