Photo Booth and a few Browsers wont open

A few days ago i changed my home screen,I moved everything from the Old Home to the new, Then Logged out of the Old and Into the New and deleted the Old. Then I had to repair permissions and then go to Get Info and Unlock permissions on almost everything (Change to read and Write), Then i discovered Photo Booth and a few Browsers wouldnt open. So i did a repair permissions again, Then it still wouldnt work so i re-installed the OS which is Snow Leopard (July 2006 Mac Mini Core Duo) and im STILL haveing the problem.......The Browsers are saying "Your Firefox profile cannot be loaded. It may be missing or inaccessible" Other browsers reaing the same, but NO PROBLEM with Safari and OmniWeb will open but wont remember Bookmarks............What do i do Next? thanks in advance
