A very useful extension for extracting videos from sites. However the interface is pretty awful and unintuitive, it requires a companion app to work, and it seems to now be adding a small QR code watermark (I've only noticed this recently, perhaps it's only for longer videos?).

There are other free tools out there that can download video and audio without having to aggregate and watermark them - like JDownloader - so I'll stick with that as much as possible but keep this as a last resort.

Excelente downloader! Gosto que dê várias opções de qualidade e parece ter um bom gerenciamento de fila caso se queira colocar vários vídeos para baixar em sequência. A interface poderia ser melhor, ter talvez uma janela popup mais user friendly e mais facilidade de escolher a pasta de download, em vez de ser uma configuração fixa que precisa ser alterada sempre na página de configurações. Mas, daquilo que se propõe a fazer - baixar vídeos de diferentes sites -, é excelente.

I discovered this add-on over five years, and it still holds the champion title in the category. With the incredible number of website/protocol/format support, the app provides the best successful rate.
For the record, I am not saying this add-on was the perfect solution. A few annoying bugs won't be your problem, but the learning curve about the setting could be a challenge.

Très bon outil, dommage qu'il soit obligé de respecter un délai de chargement sur certains sites

nice program

A good video downloader, I just think that a "reload download" button could be useful when there is a download issue.

It's a must-have add-on. Doesn't always work correctly with YT though.

Useful add-on, does a decent job. Only issue is that it tracks your downloads so that it can pop up a message every 100 downloads. It's a very creepy stalker'ish behavior and makes you wonder what else is being logged.

Ottimo componente, stabile e funzionale. Qualche difficoltà ad usare l'applicazione esterna con Fedora Linux, ma eccellente con il browser Firefox.
