This no longer works. It has worked in the past. I now only get 0 byte downloads and no video gets downloaded and of course cannot be played. No response when I asked for help or if there is anything I needed to do to make this work.
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 :)
