Firefox 3 RC1 Update broke my firefox

Little update here. I used the official mozilla launchpad repo:
https://edge.launchpad.net/~mozillateam/+archive

But now when I try to start Firefox, it gives the message another firefox process is already running, and I should close that process before I can start another.

The problem is, it keeps giving that message, even after a reboot. And I am really sure no firefox process is running.

I get the same error with the official package in the official ubuntu repo.

Couple thoughts:

If Firefox was killed badly at one point its lock file may still be there - delete the files 'lock' and '.parentlock' (you'll need 'view hidden files' on, or to do this in the terminal) in your profile folder (the one under 'Path' in /home/your_user_name/.mozilla/firefox/profiles.ini).

That error message is also the one Firefox gives when it can't find your Firefox profile (friend of mine would get this a lot when he kept his Firefox profile on a separate partition, if the partition wasn't mounted at the time).

I'd suggest taking a look at your /home/your_user_name/.mozilla/firefox/profiles.ini and checking that the Path in there goes to a real profile folder. Alternatively (if you've got your bookmarks, passwords, etc. properly backed up), just delete said profiles.ini file. It should then create a new profile for you when you next start Firefox, letting you in.

if you are sure that ffox isnt running anymore, you can remove the "lock" and "parentlock" files in your $HOME/.mozilla directory.

Remember, to be safe backup your $HOME/.mozilla directory before touching it manually.
