Después de haber ensayado cantidad de extensiones que no me sirvieron para lo que necesitaba descargar , fue la única que funcionó!!! TOTALMENTE LA MEJOR!!

Very Well!!!

一部使えないサイトはありますが、大変満足しています。便利なソフトだと思います。

эта программа решила все мои проблемы

このアドオンを利用させてもらい動画を400個ダウンロードさせてもらった。簡単な操作でだれでも手軽に使用できる。動画ファンのかた全てにお勧めできるアドオンだ。

Cette extension fonctionne parfaitement. Elle est très pratique.

Excelente Add-On, estável e cumpre o que promete.

素晴らしいサイトだから、勧めたいです。

Been using this for many years, now. An excellent extension. Does exactly what it claims. Most other extensions of this type that I have tried, appear to get confused by some media formats. That hasn't happened with DownloadHelper as yet. Highly recommend.

This app/add on is fantastic. I am an engineering student who has ALOT of online lectures to go through. I HAVE to download all of them, every class builds on the next. The videos come from alot of media, this extension is the only one that has successfully downloaded all the media from the various sources. It is much better than sketchier tools that i have used. The only time it CANT work is when the media uploads through a third party popup, ie blackboard collaborate. But no app I know of can.
