Hi Localhost, please ignore the spam message promoting an unofficial phone number.

Can you confirm there are no other Firefox processes running that could be accessing that profile folder?

Do you have a parent.lock file in any of the profile folders?

If you start up Firefox in the external Profile Manager dialog, can you successfully start in any of the profiles? More info: Profile Manager - Create, remove or switch Firefox profiles -- see the "when Firefox is closed" section.
