I'm surprised noone has mentioned the "parent.lock" or ".parentlock" 
file that Firefox keeps in the profile directory to determine whether 
it's running or not.

If Firefox dies or loses access to the profile (e.g. it's on a network 
drive) before it removes that file (which it does during a normal, 
orderly shutdown), it'll be there telling Firefox that the profile is 
"in use".

Try finding and deleting that.
