Comment 5 for bug 1659988

I fixed all the issues now.

Now the apparmor profile works:
- console output remains silent
- nothing is logged to /var/log/syslog
- firefox renders content again in tabs

Tested with ubuntu 16.04 (up-to-date) and firefox 51.0.1

Please reread the patch carefully in terms of security. I think I did not open it up too much, but in principle I just tried to get my firefox working again. Basically, I opened up everything apparmor was complaining about.
