The best have used so far. It would have been a 5-star rating were it not for a small banner/logo that is embedded on each downloaded video.

Very helpful ! I love it

Does not function since one month.
The three coloured balls stay white

The best of all I have tested

I have never been decept by downloadhelper.

It is a very useful APP.

Excelente app

Very stable. I really recommend this add-on.
Only issue that I don't feel convenient is the title of the downloaded file become as same as past one. When this happens, I always reload the page, then the page title will be the file name.

good app
