Thank's

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.

I have never been decept by downloadhelper.

good app

Works great overall. I would like to have the option that the current date is added to the video.

One of the best!!!

Addon works great but the companion app can be tricky to get working

This add-on is really good

AFAIK, it's the only usually-reliable extension one can use to DL in-page content. Lately it's had trouble capturing some streaming video, which was always one of its particular specialties. But you have to appreciate what a cat-and-mouse game this must be, as content hosts and download-utilities devs keep trying to stay ahead of each other.
As soon as VDH catches back up, I'll be glad to return here and add a 5th star. Meanwhile, thanks for the great work, guys!
