Not working? Bewertet mit 5 von 5 Sternen
I've been using this add-on for about 6 months, but seems it isn't working as of today :/
Fix it please D:
YouTube has changed video embed urls. That broke the extension. Fixed it.
However the new version (0.971) might still be in review but you can download it from https://addons.mozilla.org/en-us/firefox/addon/smartvideo-for-youtube-mytube/versions/
