unable to remove a extension from firefox << plz help me remove it!

Ok, the attached image explains it all. This extension was downloaded from the mozilla site!

I looked in C:\progarm files\mozilla firefox\extensions but only found a file named install.rdf (opend with notepad, doesnt seem to be related to the plugin)

Also, i have customizegooogle installed and that doesnt appear in that folder, am i looking in the wrong place? (i searched the firefox for 'google' and only found the search engine (the one next to the address bar, not the customizegoogle extension)
