Saw this ghacks article for speeding up YouTube on FF and seems to help.

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.

  • Welcome to the monopolization of the internet. And blatant anti-competative practices.

    Huge operators like Google can intentionally make their sites and services a worse experience for other browser users.

    • it's like the netscape thing all over again.

    • Very true, I hate that so many sites will sometimes fully load on FF and start to work right before a fake error message telling me to "try updating FF to a newer version" (even though they know it is fully updated and just want to force opening a Chromium-based browser). It doesn't help that basically all the browsers (aside from FF, forks of FF, and Safari) are all using Chromium.

      While some of them are very good, and make some actual changes for the better. It still re-enforces Google to basically pull what Microsoft did with IE. IE would probably still be alive and fucking with the internet if Microsoft had done what Google has pulled off.

      Even though original Edge was wonky, it kind of sucks that Microsoft didn't keep their own shit. But only just because it would be one less major Chromium browser (only good thing currently is that they still allow full uBO).

      Though I really hate their overlaid shit Edge puts on the Chrome download site, and the huge banner at the top of Bing search results page when searching for Chrome. I have to download Chrome on peoples' PCs a lot at work, so that shit is mildly infuriating to constantly see.

      • It really is a shame that Microsoft gave up their technical position in order to gain a market position. However, ultimately, that worked out for them.

        Microsoft didn't keep it because developing a web browser is insanely expensive, and they where too far behind. While they where trying to pivot to Azure and other cloud ecosystems.

        With likely 1000+ engineers being involved in Chrome in a meaningful way, it's an insanely expensive project, and Microsoft just couldn't keep up.

        Now given that Mozilla has an engineering team 1/4 to 1/6th the size for Firefox really puts into perspective How astronomically well they have been doing with Rust.

        This also puts into perspective how unlikely other browsers like Ladybird are to ever take off, when a year of their development is eclipsed by a few weeks of major browser development. Compounding over and over.

        Shits a mess.

  • 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.

    • I wonder if more people in testing have had issues with it like you did. Might explain why it is default false. Though it is good that you noticed that it happened after a big system update. Did you happen to notice if your Nvidia drivers also got updated along with the other system stuff? I am not a dev, coder, or anything that would give me special knowledge (just curious). Maybe the GPU or X11/Wayland might be the cause (also could just be with how FF was calling resources).

      I hope that if others run into the same issue (or similar) will share here and on any other places where the settings have been shared. Not that I expect Mozilla to see them, but could be helpful for folks to know that they might need to change it back. As it is very easy to not have issues for a while and not remember even flipping a setting if something breaks. Would also be interesting to see if issues are any more common depending on the GPU and/or the windowing systems (or OS if Windows, Mac, and BSD users also run into issues).

  • This one doesn't exist. Should I create a new one?
