This Extension is great. It does everything I need it to do (which is download whatever broadcast shows I'm interested in so that I can then watch them on my TV instead of the smaller computer screen), and just as importantly, it doesn't get in the way when I don't need it. I also like the fact that after it automatically detects the video, it allows me to choose what resolution to download the video in. I've been using it for years now, and it's definitely on my list of "must-have" Firefox Extensions when I'm configuring Firefox on a new computer (or have re-formatted my current one).
