Thanks, will take a look at that after the weekend ** This bug has been marked a duplicate of bug 1659922 Firefox 51.0.1 после обновления в Ubuntu 16.04 x32 не отображает содержимое сайтов -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to firefox in Ubuntu. https://bugs.launchpad.net/bugs/1659988 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.
