GREAT ;) Rated 5 out of 5 stars

Non funziona assolutamente ne bassa risoluzione ne HD ne video ne audio, non scarica niente

PS: now it works, GREAT ;). I installed the latest version 1.7.6 https://addons.mozilla.org/firefox/downloads/file/223290/download_youtube_videos_as_mp4-1.7.6-sm+fx.xpi?src=version-history,

before I had the 1.6 and it seems to me something before I put 1 star, Now I put 5 stars XD

This review is for a previous version of the add-on (1.6.5).
