I'm not surprised because .xpi is the wrong extension, you need to rename the .ini, .cache, and .rdf extension files:
Corrupt extension files
Files that store information about the extensions you have installed can sometimes be corrupted. Deleting them can fix a number of extension issues; they will be regenerated the next time you start Firefox. Exit Firefox completely, then open your Firefox profile folder (read the linked article for its location) and delete* these three files:
extensions.ini
extensions.cache
extensions.rdf
* 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 3 files as , 'extensionsOLD.ini', 'extensionsOLD.cache', 'extensionsOLD.rdf'
Unexpected installation error -203
Installing themes or extensions may fail with the message, Unexpected installation error -203. (If this occurs after a Software Update you may find that add-ons that were previously installed also do not work.) Follow the above directions to remove corrupt extension files. If the problem is not resolved and you use ZoneAlarm or CA Firewall, disable it temporarily (enable Windows Firewall in the interim) to allow the installation. If the problem persists, your profile may be corrupt (bug 361358). Use the Profile Manager to create a new profile or create a new default profile and then transfer your data to the newly-created profile.
