This used to work well, but at some point it became unusable. Videos only download at a horrible, blocky resolution, and they have a giant QR code appended to the top-left - and that's if you can get it to download at all. I tried downloading and converting one video, and it took over 6 hours without completing before I gave up and tried another addon (which completed it at higher quality, with no QR, in a fraction of the time).

I know things cost money and I think having free versions with limited functionality is a good way of getting people to upgrade, but that free version should at least work somewhat well. This doesn't.
