Hi. I've had this problem since November (see:
<https://lists.ubuntu.com/archives/apparmor/2016-November/010274.html>)
And it turned out that I had to add to the Firefox profile a couple of
rules (These problems occured after Firefox update to the 49/50
versions.) So, I added:
@{PROC}/[0-9]*/net/arp r,
owner /run/shm/org.chromium.* rw,
(see: <https://lists.ubuntu.com/archives/apparmor/2017-January/010445.html>)
owner @{PROC}/[0-9]*/task/ r,
owner @{PROC}/[0-9]*/task/* r,
(see: <https://lists.ubuntu.com/archives/apparmor/2017-January/010496.html>,
<https://lists.ubuntu.com/archives/apparmor/2017-January/010505.html>)
#include <abstractions/nvidia>
Everything after Firefox update and e10s enabled. Also, recently
appeared problem with "lsb_released" DENIED message (in the log files
such as, for example, /var/log/kern.log). After every first Firefox
start, there was an entry such as:
[...] audit(1486317534.042:95): apparmor="DENIED" operation="exec"
parent=4197 profile="/usr/lib/firefox/firefox{,*[^s][^h]}"
name="/usr/bin/lsb_release" pid=4198 comm="firefox" requested_mask="x"
denied_mask="x" fsuid=1000 ouid=0
I've had to add "lsb_release" child profile to the Firefox profile (see
<https://lists.ubuntu.com/archives/apparmor/2017-January/010508.html>
and
<https://lists.ubuntu.com/archives/apparmor/2017-February/010523.html>)
suggested by Mr Seth Arnold (many thanks!). After this step, mentioned
DENIED entry no longer appears.
Anyway, after Firefox update (ver. 49/50) and enabling e10s I've had to
make some changes in an official Firefox profile etc. Everything
happened on the 12.04 LTS Release.
Thanks.
