To the person calling this fake: I was a user of this a number of years ago, and can tell you it's most certainly not fake. The problem is, after the add on installs, it opens their site which has now shut down. So links to a typical inactive url advertiser.
The Add-on itself does still actually work, although a number of the features are broken, and it now looks a lot uglier than it used to. I really hope the developer updates it, as I liked some of the features of it.
