棒棒哒

It works great. Although sometimes it wont get youtube.

Es la mejor extensión que existen entre todos los navegadores disponibles en la web. La recomiendo demasiado. Gracias a firefox.

My favorite vid grabber, been running it for a long time...much thanks to the developers!

excellent addon qui permet de récupérer rapidement les videos ou sons dant j'ai besoin dans différents format, très simple d'utilisation, je recommande vivement

Don't bother. After installing the plugin it had me download an additional program. Then when I saved a youtube video it has a huge QR logo taking up 25% of the screen making the video unwatchable. They than want you to pay $28 to unlock the full version. I did a google search for youtube download and found a webiste that gave me the full 1080P video in half the time and logo free.
