Hi Thomas. Yes, you're right: "the apparmor profile shipped with ubuntu 12.04 is different from that version". I'm using 12.04 LTS Release and after Firefox has been updated to the 49/50/51 versions, I've had to add some rules to the existing Firefox profile (please see: <https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/1659922> and my last comment # 51.) Everything was related to the e10s and a new Firefox versions.
Anyway, it seems that 12.04 LTS Release have pretty old AppArmor version and rules, such like: dbus (send) bus=session peer=(name=org.a11y.Bus), and so on, mentioned by You (for example; your patch in post # 31 etc.) are not compatible with 12.04 LTS. That's all.
