Similar thing happened to me in Ubuntu 18.04. Today is the first day of
my installation of 18.04. At first Firefox worked fine. Then I was
tweaking a few things after the system upgrade to 18.04, and added the
date to the top menu bar / task bar by typing "sudo gsettings set

Thanks Olivier.
A little lagniappe for me. My Enpass plugin had quit working about 6 months
ago. Tried a bunch of stuff but could never get it to work. It's working now!

** Changed in: firefox (Ubuntu)
Assignee: Olivier Tilloy (osomon) => Chris Coulson (chrisccoulson)
** Changed in:
I just had an update come through for firefox and I am no longer seeing
the behavior that I initially reported. I still don't have a symlink in
/etc/apparmor.d/disable/.
However, firefox appears to be functioning normally and I'm not getting
the warnings about failing to lock the back buffer,
The suggested command
sudo apparmor_parser -R /etc/apparmor.d/usr.bin.firefox
doesn't work for me :/
The profile is already disabled but Firefox still doesn't work.
I get many errors like:
Unable to init server: Could not connect: Connection refu###!!!
[Parent][MessageChannel] Error:
For me the issue also appeared for a none updated version of 18.10
(installing 18.10 directly).

I upgraded a fully up-to-date 18.04 VM to 18.10 (firefox was upgraded
from 62.0.3+build1-0ubuntu0.18.04.1 to 63.0+build1-0ubuntu1) and the
symlink to the apparmor profile in /etc/apparmor.d/disable/ remained in
place.
To everyone originally affected: can you please share the following
file:
Yes, this also fixed the problem with black windows for me. The problem
began immediately after upgrade from 18.04.

Indeed, to have the firefox apparmor profile permanently disabled you
need to create a symlink to the profile itself in
/etc/apparmor.d/disable/.
I wonder what possibly removed that symlink on upgrade. Can you confirm
that this started happening right after upgrading to 18.10 ?

I didn't enable the apparmor profile either, and I haven't done a clean
install in ages.
BTW I just read https://help.ubuntu.com/lts/serverguide/apparmor.html
and learned that you need to do
sudo ln -s /etc/apparmor.d/usr.bin.firefox /etc/apparmor.d/disable/
to keep the firefox profile
Yes, that also worked for me. I never enabled it myself, so something
may have went awry during the upgrade. I didn't do a clean install if
that helps.

Thanks for the feedback Gaele. The apparmor profile should be disabled
by default, I wonder if something enabled it behind your back, or do you
remember if you did that intentionally?

Yes, Firefox is working again now. No more black windows.

To everyone affected:
Can you try running the following command in a terminal to temporarily
unload the firefox apparmor profile, then launch firefox and comment
here on whether this improves the situtation?
sudo apparmor_parser -R /etc/apparmor.d/usr.bin.firefox
Thanks in advance!

Happening to me also. Intel graphics. I've removed everything and reinstalled
it. Same.
But the Firefox Snap works fine. So do Chromium and Opera.
