This happens when you delete the Firefox profile folder and leave the profiles.ini file.

See:

  • Mac: ~/Library/Application Support/Firefox/

You can use one of these to make Firefox create/use a new default profile:

  • Delete the profiles.ini file to force Firefox to create a new default profile
  • Use the Profile Manager to create a new profile
  • Use "Choose Folder" when you create a new profile to select the location of a lost profile and recover this profile
