Yeah, it's easy, it downloads like a charm, don't need to use scary online tools anymore!

Excellent, with a special mention for the speed changing without changing the tone which is very usefull for working and transcribing music !!! I don't find it in any video player software !!!!!!

This is one sweet firefox extension, definitely one of the best I use regularly, good looking and rarely gives you any hassle.

I have been using this add-on for awhile and if I run into questions, the creator has always responded to my questions. Glad to have this one!
5/21 update - this developer has always been on top of all youtube changes and quickly resolves issues. Still a 5 star!
