very nice and useful add-on, downloaded over 500 videos with it so far and it`s my most used add-on of it`s kind.
I use several different ones for the same purpose, since none of them is able to handle all websites. on many occasions this extension succeed where other have failed.
So, while not the most intuitive to use or feature rich, it does what it claims well enough and has high success rate comparing to other similar add-ons.
