Comment 17 for bug 1593407

Hi Alberto, the audit log output when starting firefox is the following:

Sep 23 06:49:13 ub22mate audit[5486]: AVC apparmor="DENIED" operation="mkdir" profile="/snap/snapd/16778/usr/lib/snapd/snap-confine" name="/tmp/guest-tikhhx/" pid=5486 comm="snap-confine" requested_mask="c" denied_mask="c" fsuid=997 ouid=997

The permissions of the created directory are:
guest-tikhhx@ub22mate:~$ ls -la /tmp/guest-tikhhx/snap/firefox/
insgesamt 0
drwxr-xr-x 4 guest-tikhhx guest-tikhhx 100 Sep 23 06:49 .
drwx------ 3 guest-tikhhx guest-tikhhx 60 Sep 23 06:49 ..
drwxr-xr-x 2 guest-tikhhx guest-tikhhx 40 Sep 23 06:49 1860
drwxr-xr-x 2 guest-tikhhx guest-tikhhx 40 Sep 23 06:49 common
lrwxrwxrwx 1 guest-tikhhx guest-tikhhx 4 Sep 23 06:49 current -> 1860

And just to be clear: this seems to be a Snap problem, not a Firefox problem, as the Snaps of Chromium, Opera and Skype show same behaviour.
