十分好用！就是最近有的国内网站为何不能使用了

Really does work brilliantly, and rarely fails to do its job, I'm not entirely convinced of its security though, like most addons its probably worth disabling if you're doing anything sensitive.

Simplicidad y agilidad en la conversiòn. Hace todo mucho más fácil.

超好用的
使用方便，容易上手

good

Works great and on almost any website
the only downside i found was that even tho my connection was stable, any cinema movie larger than 1.5GB failed at approx. 45%

Es una aplicación escelente la utilizo muchisimo

Works well for me. Thanks. :)

Un'estensione utilissima e straodrinariamente compatibile portata avanti ed aggiornata nel corso degli anni con ottimi risultati, quasi senza rivali oggigiorno!

Awesome Add-on ... would recommend its usage to everyone cause its easy to use and grabs videos from most of the sites :)

very easy to download video content

Já baixei mais de 100 vídeos utilizando esse addon, e é um dos melhores que já utilizei.
