I mostly acquired this extension with the obvious idea that I would be able to download videos with it. When I went to the #1 video site on the entire internet and attempted to download a video, I was told that it couldn't download it, because it was somehow special, however, they could sell me a product that could. This makes it more of an opt-in advertisement extension than an actual add-on, not to mention the anti-competitive nature of such 'advertising'. Garbage.
