This add-on used to work a couple of years ago but is now just spamware. The large majority of video pages says there is no video to download when there is and then it just show an advert for its paid-for version. This applies to YouTube and about six other sites I have tried recently. On several of those, another video recorder product finds them and offers to open them in another tab (where you can right click and save them), so this is evidently by design to be spamware no longer dowload video. Whichever option you click then goes round in circles so all you can access is buying the paid version. I am deleting this extension now it is only an advert.
