Hello afzski, any luck if you rename the profiles.ini file to profiles.iniOLD, to force firefox to create a new profile ?

The profiles.ini file is inside the "Firefox" folder in the profile folder path.

thank you

You need to locate the profiles.ini file and delete this file or use the Profile Manager to create a new profile.

See:


This issue is caused by a problem with the profiles.ini file or with permissions/ownership of involved folders/files.

You can use one of these to make Firefox create a new default profile or recover an existing profile:

  • Delete the profiles.ini file to make Firefox create a new (default) profile
  • Use the Profile Manager to create a new profile
    If you still have an existing profile then click "Choose Folder" in the Profile Manager and browse to the location of a lost profile to recover this profile
    https://support.mozilla.org/kb/Managing+profiles

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

  • Windows: %AppData%\Mozilla\Firefox\
    *C:\Users\<user>\AppData\Roaming\Mozilla\Firefox\
  • Mac: *~/Library/Application Support/Firefox/
  • Linux: *~/.mozilla/firefox/

If clearing the profiles.ini file isn't working then also check the location of the cache files.

  • Windows: *C:\Users\<user>\AppData\Local\Mozilla\Firefox\Profiles\<profile>\
  • Mac: *~/Library/Caches/Firefox/Profiles/
  • Linux:*~/.cache/mozilla/firefox/

You can also try to rename/delete the Mozilla\Firefox\ folder in both above mentioned locations (main, cache).
