This is the only add-on I've ever found that can download from literally anywhere, even Chinese and Japanese sites. The only downside for some might be that for some videos and HD quality, it has you download a net.downloadhelper.coapp to your PC. I scanned it with Bitdefender and Malwarebytes and everything was fine.

excelente download mp3 movie.

No me funciona para mp4

great app works fine for high quality downloads

Video DownloadHelper ist sehr gut. Die Funktionen lassen keine Wünsche offen und es funktioniert sehr stabil und sicher. (Linux Mint)

Das AddOn tut genau das was es soll. Videos von allen möglichen Seiten Downloaden zu können. Auf YT kann man sogar die Qualli einstellen. Perfekt, genau das was ich wollte.

I'm pretty satisfied with this extension; so far trouble-free and substantially better than the kind of spotty alternatives.

Kind of bothered, though, how it handles "streaming downloads" of video files differently from "regular downloads". It'd be nice if both methods consistently used FF's download display button list, so you can see all the files you've downloaded at once, in the same place.

Another useless extension does not work no icon

Перестал скачивать видео с ютуба. Не рекомендую

Love this tool very much as it works as it is promised.

Excellent tool, does exactly what is says. Recommended,
