O que essa extensão não te conta é que ela é inútil a menos que você pague!

Works well in most cases.

Waste of time and bandwidth downloading a 6 hours video, ended up with a giant arse QR code throughout the video.

Fonctionne bien, simple à utiliser

Excelente, mejor imposible

nice features en good to use

Rather useless unless you pay almost USD30.
GIANT QR-code ruins any video.

18 bucks throw away because they are death sent on asking you to download add on and put a giant QR code on the video making it impossible to watch or use

Do not recommend.

Excelente programa

I have used VDH for several years. They update the software regularly. It has worked flawlessly for me.

It WAS an excellent addon for downloading every video and playing it off-line (especially helpful with slow or unstable Internet connection). Nevertheless, now it doesn't work with Youtube.
I'm not sure about version with functionality broken - I haven't updated it for a while. Anyway, it doesn't work now.
