Quite effective with downloading vides on many platforms but the UI is a little bit confusing to navigate at first.

Это самое лучшее приложение для скачивания видео !!!

Dels millors que he trobat.

I've just downloaded my 2200th video using this add-on and i genuinely love it.. Never has cost me a penny and apart from you tube, it downloads from pretty much every video streaming site that ive seen in over 5 years.. INCREDIBLE

Отличное расширение! Работает без проблем1

Para descargart cualquier video pide instalar una "aplicación auxiliar" sin esa aplicación auxiliar no se puede descargar ni reporducir nada. Buscaré otro complemento que realmente sirva.

easy and powerful! best add-on for video download!

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.
