kennt nicht alle Vormate wahr mal beser!

A very useful add on, which usually works well. Sometimes you have to restart a video to allow VDH to catch up!

just great

Best Firefox add-on. I've used it for years and it has gotten better over time.

I am giving one star less as i am unhappy when some of the sites are not supported for this extension. Overall, I am pritty happy with this app and this is the one i most use. This app haven't disappointed me yet. Well, may be a bit, but this acceptable. I am not a developer to know how much effort they put on to this app, but i would like to say - Good Job every one! Well done and keep going!
