This add-on is fantastic lets you download 720p videos for free without having to install very questionable programs on my pc. Just click a button under a video and it downloads. But since I'm a rich chigga and want to see further development for this add-on I donated some spare crypto currency so I can get use of the 1080p downloads.

Just a heads up if you do use crypto currency to pay for the pro version it's gonna take a while. I paid a couple days ago, didn't get to the automated page for some reason, but the developer contacted me and sent the activation email. It just took longer than expected, but still a fantastic add-on, with great service. 10/10 :*
