Uso este add-on há muitos anos e ele nunca me deixou na mão. É muito simples e prático. Realmente funciona bem.

It's flawless when it comes to downloading streamed videos. But I guess it could use some improvement when it comes to YouTube videos.

very usefully

el mejor descargador de videos. lo recomiendo ampliamente

I am using this add on for years now and it literally has saved me because i have not found a single video that cannot be saved with this addon. It's so convienient to have the ability with 2 just clicks to download so easily a video that is so interesting to see at a later time.

excelente
