How to run Firefox when your profile is missing or inaccessible If you moved, renamed, or deleted your Firefox profile folder Firefox stores your user data and settings in a special profile folder and pulls information from this folder every time you start Firefox. The default profile folder location is under the %APPDATA%\Mozilla\Firefox\Profiles folder. Profile was moved or renamed If you know where your profile is, try one of the following methods to help Firefox find it. Move the profile folder back to its original location. Restore the profile's original name if you've changed it. Create a new profile using the Profile Manager using the instructions to start the Profile Manager when Firefox is closed. Give it a descriptive name, click on the 'Choose Folder' button, and then select the profile folder you moved or renamed, before you finish the Create a new profile wizard. Profile was deleted If you deleted or lost your profile folder and have no way of restoring it, use one of these methods to create a new Firefox profile: Method 1: Use the Profile Manager wizard Follow the steps in the Profile Manager - Create, remove or switch Firefox profiles article to create a new profile.
