方便使用，大多數影片都可下載.

Fügt seit neuestem unangekündigt einen QR-Code in Videos ein, den man ausschließlich über den Erwerb einer teuren Lizenz zum Konvertieren verhindern kann. Das war's, tschüß!

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.

Funciona de maravilla, solo una o dos veces no mostró las opciones de descarga, pero es mas la página en cuestión, ya que al refrescar, se soluciona.

Without installing an external tool called a companion app, this add-on by itself cannot do anything.

Très grande compatibilité, outils polyvalents et facilité d'utilisation.
Je recommande cette application, même si elle est payante.

Muito bom esse addons, com ele consigo salvar todas as minhas séries favoritas sem nenhuma dificuldade.

Video Download Helper is one my most-used add-ons. I love it! I only remember one time in the past 10 years that it couldn't download a video and that was at least 8 years ago. I mainly use it for one-time webinars so I can go back to them later for details.

Funciona perfectamente, Fantastica aplicación

Causes a lot of lag on Youtube streams and embeds. Fails to pick up audios on some videos. Not really needed if you know how to download without it.

I use it and it works great for me. Getting videos has been very simple and fun.

這個附加元件使用起來非常方便.豐富我的生活不少

After the last couple of Firefox updates (using Linux Mint) the apps started to download, only to find that there can be only a couple of minutes actually downloaded.
Tried to use this app on LibreWolf (tired of Firefox changing my settings for IPv6) but claims the video extension isn’t installed.
Used to be perfect, doesn't work on Librewolf so for me it's now useless.
Update,
Now even worse with this quick download nonsense telling you that it will download where it wants too.
Removed, may also change browsers as non of the video add-ons work as claimed mainly due to Mozilla.org.

Downloads every video perfectly each time.

Fuck your extension. It sucks. In 50% of cases it doesn't download the whole video. And what is this ADP bullshit and convert for YouTube videos. I can literly use a YouTube downloader website and it downloas an .mp4 video in in its entirety with sound and video with no watermark. So yeah, fuck You and your extension.
