This is a great add-on for YouTube Video downloads. It's very easy to use and very efficient as well. I highly recommend this extension.

the best

New version is pretty nice. Just wish you could disable the popup window that notifies the download is complete, there's already the built in status widget on the page and Firefox's own download manager popping up at the top. And if we could edit the download options to e.g. remove all the MP4 options so the drop down is shorter would be nice too.

work flawlessly

Excellent - works well
