Danke Schön Rated 5 out of 5 stars

Dude! What a great job, very neat! Are you some kind of genius ;) ?Anyway, a very cool feature would be the possibility to make the html5 reading automatic (I'm bored clicking for each video).BTW, works great on Linux Mint 13 Mate.Edit: So now I have to give you 5 stars and not 4. You roxxxxxx as firefox

This review is for a previous version of the add-on (0.1.1-signed). 

Thank you very much! :-)
Have a look at the new version 1.0.1 which has automatic playback by default. (and much more..) It is in the review queue of mozilla so it does not yet appear by default. But you can already find it on the "Version Information" page:
