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

See:


This can be caused by a problem with the profiles.ini file and the profile marked as Default=1 in this file is no longer present on the hard drive.

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

  • Delete the profiles.ini file to force Firefox to 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 PM and select the location of a lost profile and recover this profile.

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

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

Windows hides some file extensions by default. Among them .html and .ini and .js and .txt, so you may only see a file name without file extension. You can check the actual file extension (type) in the properties of the file via the right-click context menu in Windows Explorer.

Did you type the full path?

  • %AppData%\Mozilla\Firefox\

Do you see a Profiles file in that location?
