[Bug 1857940] [NEW] apparmor prevents firefox from sending mails

[Hadmut Danisch]

Public bug reported:

since activating apparmor, the send link mail function (you need to
customize the tool bar and add the letter symbol) does not work anymore.

Reason:

kernel: [14170.598883] audit: type=1400 audit(1577746984.736:820):
apparmor="DENIED" operation="exec"
profile="/usr/lib/firefox/firefox{,*[^s][^h]}" name="/usr/lib/x86_64
-linux-gnu/glib-2.0/gio-launch-desktop" pid=12565 comm="firefox"
requested_mask="x" denied_mask="x" fsuid=1000 ouid=0


apparmor keeps firefox from launching 
/usr/lib/x86_64-linux-gnu/glib-2.0/gio-launch-desktop", "thunderbird", "mailto:?body=https%3A%2F ...


I'm not absolutely sure, whether this is a bug or security-intentional
behaviour, but in general, firefox should work or have special apparmor
proof mail programs.
