Comment:
Unless there's other parts of Firefox that also puke when MIT-SHM isn't
available, I assume this is the libcario bug described in
https://bugzilla.mozilla.org/show_bug.cgi?id=1271100#c20
There's mitigations/workarounds for this (that are also applied in newer
firefox), by hooking `XQueryExtension` and `XShmQueryExtension`. If your
libcario2 is at version 1.14.8, then I suggest bringing it up with the
Firefox developers.
There likely isn't anything more I can do with this, since I don't have a
system that can reproduce this anymore (the mitigations I applied were
sufficient to squash it when I saw it, and it's a race condition so it's
hard to reproduce reliably to begin with), and it's either a firefox or
library bug.
