I didn't enable the apparmor profile either, and I haven't done a clean install in ages.
BTW I just read https://help.ubuntu.com/lts/serverguide/apparmor.html and learned that you need to do
sudo ln -s /etc/apparmor.d/usr.bin.firefox /etc/apparmor.d/disable/
to keep the firefox profile disabled (otherwise it will reappear after a reboot).
