Usually a great add-on, but it can't see all YouTube videos. For instance not this: https://www.youtube.com/watch?v=ToXNDnBUa5A It's also a bit worrying that it want permission to access and modify almost everything.
Addition Jan 1, 2020: I will give your app one more star because I believe you when you say you have fixed the problem. But I installed the other add-on "Download Video & Flash", so I haven't tested your new version... ;-)
