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.

Excellent - works well

Easy to use. (Update) Says the video has been downloaded but the file is created but no data is downloaded. After it says video has been downloaded, it says Video is being processed but nothing changes. There is no video to play and under VLC it simply gives the series of errors as there is no data.
I hope this can be fixed.

one of the few extensions that ACTUALLY downloads
and they do it with multiple definitions and languages!
