As of a month or so ago, I've been experiencing a growing number of
crashes with Firefox on -current, including with 142.0 in ports. I have
no idea what's causing them other than that I see this sort of thing in
the terminal at the point of exit:

  Exiting due to channel error.

  Crash Annotation GraphicsCriticalError: |[C0][GFX1-]: CompositorBridgeChild receives IPC close with reason=AbnormalShutdown (t=108.119) Exiting due to channel error.

Sometimes I can go an hour or two with out a crash. Other times I might get
3 or 4 crashes in a minute.

Compared to a lot of people I know, I'm not a massively heavy user of
browsers: there's heap and stack space to spare for the browser. I've
recreated my profile from scratch (I use a few extensions, but otherwise
virtually no customisation) and the problem manifests on two separate amd64
machines. Perhaps the fact that I'm using XFCE is relevant? I'm unsure!

Has anyone else seen something similar?
