  [Where problems could occur]
  
+ The fix adds additional paths to firefox apparmor profile (e.g. affecting /sys/devices/pci* and RealtimeKit1). When using deb version of firefox the browser may chose a different code path to execute than before, so it may affect hw acceleration (the sysfs paths were used by libxul) and audio.
+ Maybe rendering artifacts and audio sync issues in videos.
