Works as advertised; not the fastest in the world but it does exactly as expected.

this addon works perfect, defaults to 128kbps mp3's. it does take some time to fetch and encode the audio, roughly 1 min on 3 min video, if its a longer video it will take longer. addon does all the downloading and encoding with 1 click and doesn't take you to any other websites. file gets saved to your specified downloads folder. all other addons didn't work or took me to websites to run everything through.

Anfangs war der Downloader ganz gut, hat getan, was er soll.
Jetzt kommt immer ein Umleitungsfehler, es funktioniert also gar nichts mehr. Deshalb kann ich auch nicht mehr als einen Stern geben.

Does not bloody work at all waste of time ...Where the heck is the dowload button on youtube mozilla you are full of it BS

It works, one click then all you need to do is select where to save (though it seems it won't remember the save path), no dirty porno ads, no pop up crap, 5 different bit rate to choose from 96 to 320. For a free add on, this is very nice. If the author would update it to make it remember last save path it'd perfect !

It works, but slowly. My main complaint is that the file name it saves includes the date and that it was saved from youtube (both not important to me) and cuts out the song and author info (info I do need) - If that could be changed - it would be so much better!

Después de mucho buscar una extensión práctica para descargar mp3 de YouTube, encontré esta. Muy funcional.
