The problem with all these Firefox forks is most of them are dead ends, development wise. They don’t contribute upstream. Maybe Tor excluded.

Hopefully this one is different, it does seem to have some actual code behind it rather than just disabling features.

Mostly that it doesn’t work on Steam Deck. Hits memory limits IIRC.

I haven’t used it because most games don’t work or have as good of performance. Benefits in short term will be things like in-tree kernel module, better working relationship and bug fixes with open projects like KDE/Gnome and maybe things like Gamescope or VR.

Now, if you want. There will probably always be tradeoffs between the two drivers so I doubt this will ever match Nvidia’s across the board, just have to pick your poisons.
