Comment 9 for bug 1521789

Going on skomorokh's advice I downloaded the apparmor tools to put things into complain mode and so forth.

Theoretically this should not have fixed firefox, but it seems to have done so for me. Firefox always used to freeze within minutes for me. Now it hasn't frozen in days. I didn't do anything other than install the apparmor-profiles and apparmor-utils packages and tinker with complain a little. I did *not* note what files it complained about nor did I whitelist any. Yet it started working, and has done so for the past few days.
