Default Profile usr.bin.firefox requires additional rules for Xubuntu 14.04

[Kaosu]

Release: Xubuntu 14.04
Version: AppArmor 2.8.95~2430-0ubuntu5, FireFox 29.0+build1-0ubuntu0.14.04.2

What you expected to happen: Firefox to run without errors when setting usr.bin.firefox to enforce mode with the default profile.

What happened instead: Constant "DENIED" errors were sent to /var/log/kern.log and FireFox did not work properly with XFCE

Solution:

The following additional rule must be added to usr.bin.firefox for proper operation when using Xubuntu 14.04:

/etc/xfce4/defaults.list r, #Xubuntu 14.04 fix
