You can check for issues with your Mac user account.


There might be a problem with permissions/ownership of involved folders/files preventing access. You can check for problems with the profiles.ini file that registers profiles.

See:


You can try these steps:

You can find the profiles.ini file in this hidden location:

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

You can recover an orphaned profile via these steps:

See "Profile was moved or renamed":

Note that you should never use "Choose Folder" to specify a folder that already contains files that do not belong to Firefox. Only use "Choose Folder" to recover an profile that isn't listed in the Profile Manager.

If this didn't work then check the read/write permissions and owner or remove the Mozilla/Firefox folder in both main/root and local/cache locations.

Location of the cache files.

  • Mac: ~/Library/Caches/Firefox/Profiles/
