I'm getting the "Your Firefox profile cannot be loaded" error. None of the solutions on this site are working. The Profile Manager doesn't open and when I try to delete profiles.ini, it's not there. I have my computer set to show hidden files and it isn't there at all.

Were you able to locate the profiles.ini file?

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/
