FireFox Error

Apologies.  This is a tech post.  I googled the hell out of this problem and never found a solid resolution.  After fiddling around, I was able to solve this problem repeatedly using this solution.

The error occurring looks like this from FireFox version 14:

A copy of Firefox is already open. Only one copy of Firefox can be open at a time.

This was happening to every account on a machine running Mac OS X Snow Leopard Version 10.6.8

To resolve the problem, navigate to each user's Library/Application Support/Firefox/Profiles folder.

There was only one directory within the profiles folder in the format of XXXXXXXX.default.

Copy that file to the desktop and then delete it from the Profiles directory.

Run Firefox.

You should get an error that reads: "Profile Missing.  Your Firefox profile cannot be loaded.  It may be missing or inaccessible."

Click "OK" and move the XXXXXXXX.default directory back to the Library/Application Support/Firefox/Profiles folder.

Run Firefox, and Voila! It should be running without a problem.

I have not clue why this works, but I hope it helps some of you get past the problem.
