Use the Profile Manager to create a new profile.Delete the profiles.ini file to make Firefox create a new (default) profile.You can use one of these to make Firefox create a new default profile or recover an existing profile: Installed extensions and other customizations (toolbars, prefs) that you have made are lost and need to be redone. The current profile folder will be moved to an 'Old Firefox Data' folder on the desktop.
When you Refresh/Reset Firefox then a new profile is created and some personal data (bookmarks, history, cookies, passwords, form data) is automatically imported. Do you have an 'Old Firefox Data' folder on the desktop?
