I was using Firefox exclusively for years, but when I sold my Macbook and bought a Thinkpad and installed Linux on it, I grew pretty annoyed by Firefox.

Specifically, I couldn't view my 360 videos or photos on Google Images or Immich at anywhere near acceptable performance. The videos, recorded at 30fps, would get maybe 5fps. This was weird, because I have a fairly beefy laptop, it should be able to handle these videos just fine (especially since my iPhone handled it just fine).

After a bit of debugging, it appears that there's a bug in how it's writing for the shader cache, and as such there was no hardware acceleration. I found a bug filed about my issue [1], and I didn't really feel like trying to fix it, because I didn't want to mess with Mesa drivers. I just installed Chromium and that's what I'm using right now, and it worked with my 360 videos and photos absolutely fine.

I want Firefox to succeed, but that really left a bad taste in my mouth; it's not like it's weird to want my browser to be hardware accelerated.
