Public bug reported:
Since a recent update, firefox cannot any more save pages, images or
download files. It also cannot launch other processes like zoom via
meeting links. This seems to be caused by a faulty apparmor
configuration and a common problem since the introduction of the snap
package, e.g. c.f. https://arstechnica.com/civis/threads/snap-based-
firefox-is-a-terrible-experience.1487499 or
https://ubuntuforums.org/showthread.php?t=2476758 . However, none of the
proposed workarounds works for me, neither editing apparmor
configuration files, reinstalling firefox, or refreshing it via Help ->
More troubleshoot information -> Refresh firefox.
Finally, I found that snap installs two binaries, one in
/usr/bin/firefox and one in /snap/firefox/3252/usr/lib/firefox/firefox.
If I start firefox from cli with typing firefox, the first one is
invoked, which is broken. If I explicitly invoke
/snap/firefox/3252/usr/lib/firefox/firefox, saving works fine. So I just
aliased the second binary to firefox in the .bashrc. This binary also
strangely seems to use its own configuration, i.e. own apps, password
storage, etc. I hope this information helps other users with the same
problem and the package maintainers with fixing the configuration.
