Won't download anything. Try either of the mp3's and you get a popup saying youtube has changed the way they handle video files and the mp4 shows a zero byte file.
Pls. update to latest v 15.7, whenever youtube changes code every downloader out their breaks. This time it took longer for me to fix and then ever longer for mozilla to review and approve the update. If you find the addon working again, pls. re-rate the extension :)
