The crash here is caused by driver misconfiguration, at least https://crash-stats.mozilla.org/report/index/a2d555e5-5d4a-44ee-80f4-b68a70231210 From the bactrace and gfx info you use your primary Intel GFX / Mesa but dmabuf creation is redirected to NV drivers component libnvidia-allocator.so.1 So just remove libnvidia-allocator.so.1 file (and related ones). I guess it's broken NVIDIA binary driver setup here as this setup can't work. Looks like NVIDIA binary uninstall was incomplete or broken or so. Also 'consistent reproduction' indicates it.
