I found that DLHelper cannot translate or convert everything. That's why I thought maybe I can contribute something to improve the quality.

It takes a while to set up and you NEED the app to process videos properly. After installing tho, it's been working for years without ever complaining. Still going strong, still awesome

It is very useful and good add-on.

Very good add on.

easy to use and user friendly

操作使用简单、下载视频效率高，谢谢开发者。

El mejor y mas completo programa para bajar videos de internet.

Endlich ein Programm, dass auf vielen Webseiten funktioniert.

one of the best

For me is the best video downloader ever; is the only that could download ALL kinds of video!!

Works great for downloading video files from sites that don't "technically" allow video downloads. Even if the site does allow downloads, I just use this add-on. Honestly better than any other video downloader I've tried.

This Add-on is really excellent. Just one click, we can download file.
