Yeah, it's totally anecdotal and just my experience. I would really like to use Firefox. I may try it again. Quantum made such a big improvement on Linux which is why I gave it a shot and stuck with it so long. But it still had issues for me.
Hmm...that is super strange then. Intel has definitely been the most solid for me when it comes to GPU stability, including in Firefox. I primarily use a workstation with an AMD GPU, but have a secondary laptop with Intel and had no issues with Firefox there whatsoever. I am also on Arch. The only time I ever experienced frequent crashes was when I was testing the Wayland build early on, (they still happen sometimes on Wayland, which is still experimental in Firefox, but on X things have been solid for me).
I am honestly perplexed what the issue could be then, I was sure you were using an NVidia with the proprietary drivers or something like that, as such setups have caused me trouble in the past.
The only thing is I wouldn't recommend turning on WebRender for everything yet, but it's not on by default so I doubt you had it on.
