Ubuntu thinks Firefox is running when it isn't.

[Constantine Evans]

You probably had Firefox crash in a particularly unfortunate way, or had 
a power failure, which left the lock file in your Firefox profile. If 
you delete the lock file, which is ~/.mozilla/firefox/{garbled nonsense 
here}.default/lock, then Firefox should run again.

Incidentally, does anyone know why Firefox has the hash for the 
directory first, which breaks tab completion?
