I have been using this add on for a number of years and have not had any issues. It is straight forward to use and provides a numberof options.

有一定局限性，但大部分的时候是比较可靠的

Simple to use & simply fantastic❣

Funktioniert perfekt (nur um bereits heruntergeladene Dateien nochmal zu laden, kann man z.B. den privaten Modus verwenden)

Bullshit extension, most of the time it fails or only downloads part of the vid.

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.

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.
