Try resetting the Extension Manager. With Firefox closed, rename the following files in your profile folder: extensions.cache extensions.ini extensions.rdf and compatibility.ini They'll be re-created when you open Firefox.

Note : Although unwanted files/folders can be deleted, renaming them is generally considered a safer option. This achieves the same result, but allows the user to retrieve any possibly required information from them later on. In the case above, rename the above 4 files as , 'extensionsOLD.ini', 'extensionsOLD.cache', 'extensionsOLD.rdf, 'compatibilityOLD.ini'
