The PRO version works perfectly. I love to download the high quality mp3 (256kbps) of some videos or musics on youtube then sync them to my iphone. Once I got a small issue with the PRO account, I just simply wrote to the author and he replied me so quickly to help solve it.

Add-on works well and creator responds in a timely and helpful way to questions & feedback.

free version doesnt download anything at all, wasted three minutes of my time

Only a tease and doesn't work unless you pay $10 for pro version.

Its awesome .. working fine ..easy, efficient, get the job done

Free version is just as a tease, to lure people to check it. Doesnt work. Everything requires payment.

It's stopping youtube videos after 1-3seconds runtime in Firefox right now.
