@thomas303 Thank you very much! The system was not broken, because I
disabled apparmor for Firefox as you said in the opening post (altough
you intended it just for testing). Anyway, your instructions were very
complete, and my doubt was mainly compatibility with Ubuntu update. But
as you said, "Now that the original profile file remains unchanged, apt-
get won't complain when the official package gets updated.", so it's
fine for me. And it works like a charm, by the way!

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:
Confirmed
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.
