Where all else (extensions) fails, this add-on comes through - whether of a live-stream or streaming (mu3) or regular mp4 video - without fail. Only quibble is that the interface or menu isn't as familiar as other downloading apps, and the interface could appear complicated with technical listings (video often referenced as a code of numbers and letters than understandable words). But if you can decipher (even guess) the lines, it's a reliable app to download videos even when standard downloading apps stumble and fail, especially with the streaming videos.
