Mozilla lock file

OK, my computer lost power in an electrical storm and (thank god) nothing was damaged. However, mozilla was open at the time and now I can't start it up anymore without it asking to specify a new profile, saying that the "default" profile is in use.

IIRC Mozilla/netscape have a lock file for particular users. Where does this lock file exist so I can delete it and move on?

On my computer, it's in [/i]/home/ideamagnate/.mozilla/ideamagnate/hk63gayc.s/lock[/i]. Don't ask me what hk63gayc.s means.

This from the Mozilla 1.0 FAQ, explaining what the hk63gayc.s means.

7.4. What is the @$%#@$%#.slt directory in my profile directory?

This is called “salting.” Profile data is stored in a randomly named directory to make it difficult for malicious programs to find profile data (see bug 56002 and 97180)
