I have not been able to get this extension to detect a video on a single website.

I've tried this off & on for over a year & have NOT ONCE managed to download anything. All I ever get is "No media found".
Others apparently have but I see no reason why it shouldn't work for me specifically. (Firefox/WaterFox)

Doesn't work for YouTube, thanks for wasting my time

didn't work on YT. "error"
