If you are unable to uninstall an extension, even after restarting your Mozilla application in Safe Mode:Įxit your Mozilla application, go to your profile folder and open the 'extensions' directory. You may also have to delete the 'compatibility.ini' file to rebuild some other files in the profile folder. Deleted or renamed files will be regenerated upon application restart, as needed. Note: The specific extensions.* files that the profile folder includes will depend on your Mozilla application and version. To resolve this, open the Profile folder (which you can do from the button in the Application Basics section of the 'Help -> Troubleshooting Information' page) and then close your Mozilla application and delete (or rename) these files: It's possible that the files that store information about your installed extensions are corrupt, preventing you from viewing, updating, or uninstalling extensions.

If the add-on repeatedly shows 'This item will be uninstalled after you restart Firefox' even after restarting, either create a new profile or try uninstalling manually (see below).To uninstall a locked add-on, you'll first have to unlock it via Safe Mode.
