Try to delete the file profiles.ini to force Firefox to create a new default profile.

You can try to rename (move) the Mozilla or Mozilla\Firefox folder if you have other Mozilla Applications (Thunderbird).

  • Vista/Windows 7: C:\Users\<user>\AppData\Roaming\Mozilla\Firefox\Profiles\<profile>\
  • Windows: %AppData%\Mozilla\Firefox\Profiles\<profile>\

"Application Data" in XP/Win2K and "AppData" in Vista/Windows 7 are hidden folders, use %APPDATA% in the File name field.
