Don't bother installing this app. It adds a large QR Code obscuring part of the saved video, unless you pay them $28.50 for the premium version. It also makes you install software onto your computer (twice) before it works. There's plenty of other totally free extensions and software out there that will save your video for free without adding a QR Code. Maybe if the price was closer to $5 then I would consider paying. $28 is ridiculous.
