Accidentally deleted firefox "profiles.ini" and now says firefox is already running when I try to open it. "a copy of firefox is already open. only one copy of firefox can be open at one time. Now I'm aware this happens often and people have posted solutions to this, but this situation is slightly different. The "profiles" that possibly had parental lock on it were deleted and I don't know how to get it back. Re-downloading firefox obviously does nothing. Opening the task manager and to try and close all mozilla/firefox files and apps doesn't work either. Tried using Onyx to turn invisible files visible but that didn't work either. I think it's cause I deleted the profiles. Suggestions?
