Your Firefox profile cannot be loaded. It may be missing or inaccessible


I keep getting this error message. I am not able to make a new profile as I cannot open Mozilla at all. I have even uninstalled and reinstalled.

Additional System Details

Try to delete the profiles.ini file to force Firefox to create a new default profile.

Can't you launch the Profile Manager by adding a space and the -P switch to the command line?

See "Creating a profile":

I changed my ini file, all you need to fix it. Find the location C:\Users\Marian\AppData\Roaming\Mozilla\Firefos, open the ini file in notepad, then open the location C:\Users\Marian\AppData\Roaming\Mozilla\Firefox\Profiles, and see how Mozilla called a profile, may be more than one. It should be something like this rjuijto8.default. Makes your ini file should look like this   [General] StartWithLastProfile = 1

[Profile0] Name = default IsRelative = 1 Path = Profiles/rjuijto8.default

If you have more than one profile Try to change the ini file until you see that your settings.
