I was running Firefox in Wayland just fine with my AMD Radeon 6650 XT but recently switched to an Nvidia 4060 Ti (16GB) and suddenly I started having crashes. I don't blame Firefox for this since other applications started giving me issues too (e.g. Dolphin and Discord). I place the blame squarely on Nvidia.

Nvidia's drivers suck but if you want to do AI stuff their cards are basically the only option until Intel and AMD complete ramping up their support for AI stuff. I wouldn't be surprised if two years from now AMD takes the crown with Intel being a close second (providing the best bang-for-the-buck) but for that to happen AMD needs to focus more on making actual implementations faster (e.g. PyTorch) and not just making minor incremental improvements to ROCm (and also make it so you don't need to use `amdgpu-install` to use it!).

Ah, well, Nvidia still has a lot of problems with Wayland I hear, that might not be Firefox's (or Wayland's) error.

That's strange. I use Nvidia, on Wayland and have 0 issues with Firefox

I’m using an amd card :(
