Ok, so I followed the recommendations from this page and disabled
hardware acceleration. It seems to fix the problem.
Indeed it did! Disabling hardware acceleration fixed this issue.
Thanks for the pointer!
systemd-logind revokes permissions to /dev/dri/* on change of active user.
This could be why the issue doesn't crop up when running through vnc /
xpra. Probably firefox doesn't use hardware acceleration when using
those x-servers.
I have no idea if your security model allows to add users to the "video"
groups, but as a side effect, I would expect higher probability of
crashes due to bugs in graphics drivers.
My user account was already a member of the "video" group. Shall have
to see if the disabled hardware acceleration has any noticeable effect
on performance.
Thanks,

I too have been plagued by FF freezing halfway between tabs, locking up
the whole machine, so I've now done as instructed by the above links.
We'll see if that extends my uptimes. If so, thank you very much.
