After an off-list suggestion, I disabled hardware acceleration (in
settings) in Firefox and had no crashes for 10 days. I turned hardware
acceleration off and have had 3 crashes in an hour.

I don't really know what might have happened around v142ish that might
interact badly with my graphics hardware: I'm using standard AMD integrated
graphics on a 9xxx CPU, normal xorg, and XFCE.

I'm doubly surprised that it ends up causing crashes like the one below. If
anyone has any suggestions for what I might be able to do to fix this, I'm
all ears, as I don't think I have anything unusual in my setup, and so I
guess other people must also be seeing their Firefox randomly crash?
