I uninstalled Firefox from my computer, then I reinstalled it and tried to run it, but this message appeared, "Your Firefox profile cannot be loaded. It may be missing or inaccessible" and Firefox does not open at all.

I tried press windows-key+R on my computer and open %appdata%\Mozilla\ -and rename the folder labelled "Firefox" but it said "The action cant be complete because the folder or file in it is open in another program" i dont open it and try to restart the pc but still no helps

Chosen solution

A likely cause is 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.

  • Windows: %AppData%\Mozilla\Firefox\
    C:\Users\<user>\AppData\Roaming\Mozilla\Firefox\Profiles\<profile>\
  • Linux: ~/.mozilla/firefox/
  • 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
