Minimally works. Videos start playing for less than a second before the extension actually does its job which allows the video to be registered in YouTube's watch history. If this was coded to activate before the video player was fully loaded, it would be perfect.

Works on Ubuntu Linux LTS 18.04.01 tested =) Thanks =) (and no blank screen, please do take out screencapture and put a newer version, as us users can't update it, thanks)

Does not work. :( Or perhaps it does, but not in a way that I hoped it would. :/
