My test was wrong (had another instance open with profile disabled)
The patch still does not fix the problem with white/black tabs, not
rendering any content.
In syslog, I get:

Title:
Firefox apparmor profile: /usr/bin/python3: error while loading shared
libraries: cannot apply additional memory protection after relocation:
Permission denied
Status in firefox package in Ubuntu:
New
Bug description:
When I start Firefox, even when run as root, I get an error message:
/usr/bin/python3: error while loading shared libraries: cannot apply
additional memory protection after relocation: Permission denied
As a result, Firefox only shows white or black content in browser tab
(which is basically rendered empty).
I can work around this issue with a
cd /etc/apparmor.d/disable
ln -s ./../usr.bin.firefox
apt-get install --reinstall --purge apparmor libapparmor-perl libapparmor1
After that, content is rendered again.
I had this problem earlier
(https://bugs.launchpad.net/firefox/+bug/1643200) and worked around it
by installing a firefox extension "ubuntu modifications". But after
updating from 51.0.0 to 51.0.1, I got the same problem again and
enabling or disabling the extension did not help any more. Same for
enabling/disabling all the hardware acceleration and/or e10s settings
in about:config.
Now that it seems to be an apparmor profile issue, I think that can be
fixed in a nice manner. And it also should see some priority.
Therefore, I think it makes sense to have a clean new ticket for this.
