I've been using this amazing helper for a very long time now (4+ years) and it has consistently met my expectations. This helper supports so many sites and really brings out all the stops to grab those videos for you. And it's been free this whole time!? Unbelievable!

Thanksgiving has come and now's a good time to express my appreciation by leaving a rating and a small donation!

*Warning to those wanting to use this for keeping Youtube videos: Don't use this add-on because downloading from Youtube will require you to also download a companion app and slap a watermark on your video. I haven't seen this watermark slapped on any other videos I've downloaded from other sites, just seems to be Youtube.

Descargaba muy bien y sin problemas hasta que me pidieron dinero y como no dí me da muchos problemas y no puedo descargar muchos de los vídeos. O ES GRATIS O ES DE PAGO.

good

Works pretty well.

非常好的体验，可以帮助下载很多资源

es un buen producto y muy eficiente

DO NOT USE. Absolute scam. Requires you to install their software (could be a virus), took a long time to download, and then had a massive QR code in the corner... the only way to remove the code is to pay them. Use another addon or just use the online video downloaders.

Nice UI and rapid download speed. Hope to have additional wrap up or batch function upgrade in the future. Thank you.

Simply does not work.
After installation I tried to download a video from YT (a free video; no music; no film; etc.). DownloadHelper asked me to install a companion file. After some research and re-thinking I pressed the button and there was -- nothing. An error message appeared (from github) that there was no such a repository.
So, that's it for me: I uninstalled this add-on.

Awesome video downloader. Will download almost any video from the internet. Would recommend to anyone.

The only reason for not using this superb add-on would be not knowing about it. OK, now you know!
And the only reason to criticize it is most likely lacking elementary computer skills. If you read this short review and trust it, you probably not among those.

It easy to use once you get familiar with its UI, has few issues and gets updated regularly as far as I noticed. It supports many sites, way more than described. Be advised, for best results, especially when you need to convert video/audio formats, use a support application, referred to as "Companion App", which can be downloaded separately.

This being said, it is by far one of the best add-ons I ever used, both on Firefox and on Chrome (or derived from it). I like it a lot and would recommend it as a must for all those willing to enjoy the streamed content off-line.

El mejor complemento, una vez que aprendes lo detalles de como usarlo en ciertas paginas,

下载的视频没有声音

This app is Amazing!... Best video downloader I've used without spending an arm and a leg.

ダウンロードできないところhttps://vjav.com/も簡単にできるといいのですがよろしくお願いします。

Used to be great..now is terrible. The companion app constantly needs updating; however it never lets you know. The aggregating is a HUGE problem; it take hours to do this!! FIREFOX; please recommend another BETTER app!!

gutes addon

我经常使用它下载小视频

目前用過最好用的火狐影音下載套件，直覺又方便

使用感很好，支持，要是能够做到bilibili下载就更完美了

Очень выручает в обучении. Спасибо!
