[xubuntu-users] Xubuntu 24.04.1: Firefox fails to start

[Jeffery Small]

Firefox was working fine on Xubuntu 22.04. The OS upgrade completely failed
and I am now rebuilding a new Xubuntu 24.04.1 system. I uninstalled the
snap package and installed the latest version of Firefox from the *mozillateam
ppa* (131.0.2+build1-0ubuntu0.24.04.1~mt1). Any attempt to start
/usr/bin/firefox results in the pop-up message:

"Your Firefox profile cannot be loaded. It may be missing or inaccessible."

This is not true. The same profiles exist in ~/.mozilla/firefox and even
attempting to specify a specific profile with -P fails. This problem seems
commonly reported on other versions of Linux but not Ubuntu. I tried
removing the entire ~/.mozilla directory but that did nothing. I tried
starting in safe mode, but same results. However, there are also other
start-up messages:

None of this makes sense as all these files exist and are readable.  This
may be an underlying gtk problem.

Has anyone else run across this and any suggestions as to what needs to be
done.

Thanks.
