My profile keeps disappearing after I close Firefox. In order to open it back up, I have to keep re-creating a new one. How to fix?

I've already uninstalled, and reinstalled Firefox, and no dice. If I don't re-create the new profile, I get the error message that the profile is missing or inaccessible when trying to open firefox. I have to open the browser by clicking on the new profile I just created in the profile manager box.

This can be caused by a problem with the profiles.ini file.

It is probably best to delete the profiles.ini file to force Firefox to create a new default profile

You can use this button to go to the currently used Firefox profile folder:

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

Well, if you have already lost your profile, try to delete entirely Firefox from your computer : https://support.mozilla.org/en-US/kb/uninstall-firefox-from-your-computer (or search "delete entirely Firefox" on the web).

After that, check your firewall, your antivirus and your antimalware. It is time to make a security check-up of your computer, to be sure it is clean.

Then download again Firefox, from the official website, and try again to see if the problem is still here.
