This is probably a different html issue from the one I've been dealing
with. But I'll describe my problem and solution in case it helps
someone else.
When I upgraded to Ubuntu 22.04LTS, firefox stopped displaying emails
from emacs. Emacs wrote a file like /tmp/<filename>, and firefox
couldn't access it.
It turns out that 22.04 installs firefox from a snap, and snap programs
can't access /tmp files. (They claim to be able to access files in
/home, but I wasn't able to verify that.)
The solution I'm using is the one described here:
<https://www.omgubuntu.co.uk/2022/04/how-to-install-firefox-deb-apt-ubuntu-22-04>.
I had done something like this a few weeks ago, and when I sat down at
the computer this morning, after updating software without thinking, I
was back not being able to access the /tmp files. This version does
some pinning and adding instructions to unattended upgrades, that I
don't remember doing before, so maybe it won't "upgrade" me again.
