Firefox reset when restarting application after crash.

[Renamon Toast Crunch]

EDIT: Recreated the issue and discovered the following happens when Firefox is run as superuser then closed. When this happens Firefox resets when opened again as a normal user. Hope this helps.

Running firefox -p from terminal returns this error when loading default profile.
