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

best plugin i have used

Helps a lot in my day to day study.Highly recommended.

Fastastic app for download videos

it works so flawlessly, it's incredible (also bought the license since downloading mp3 files with this extension is just soooo much easier and waaaaaay more convenient)

Der Video Downloadhelper ist hervorragend !!! Ich nutze ihn sehr gerne.

This Firefox add-on has worked flawlessly. I've been using it off and on for a couple of years, and it has steadily improved. The interface is easy to use. A particular download may stall occasionally, but canceling re-starts and completes the download.
