They put a huge watermark on downloaded videos and want you to pay $28 to use the plugin. No thanks! Will be uninstalling immediately.

VDH Will install in the newest Netscape, (on Win 10), but it wont install ihe icon on the toolbar to have it work.
I depend on it now I'm at a loss.
It's also lot listed in the group of drag and drop icons.

It doesn't work when you first install it, then tells you to download some other app, then still doesn't work - cannot detect any media playing. FAQ/support is snide and condescending. Plenty of other addons do this better, with no need to download anything, far better success downloading videos, and friendly support. Why is this recommended by mozilla?

Won't download most files without an external app, which isn't mentioned in description. After downloading and spending 30+ min converting, it then informs you it has put a QR code watermark on the video (again, not mentioned anywhere prior.) Complete bait and switch.

Do you want money?! Suck my dick, asshole!

WORTHLESS PIECE OF CRAP. You CANNOT leave the current active window or it interrupts the downloading process! PI** POOR SOFTWARE ENGINEERING!!!

This addon sucks up memory during YouTube live steams. Until this is fixed I have to disable it and give it 1 star.

Describtion hides the fact that you need to install additional software. Then it tells you to get a licence ... just don't ...

Installed add-on, downloaded video, video embedded with large QR code by DownloadHelper, deleted add-on.

Por muchos años esta fue, a mi parecer, la extensión por excelencia para la descarga de multimedia. Lamentablemente, poco a poco se fue denigrando hasta convertirse en una especie de cajita registradora donde cada función debe pagarse y donde el desarrollador mantiene vínculos con las principales páginas web para evitar su uso en ellas. Su implementación y su funcionalidad (cuando se puede usar) es nefasta, hace falta descargar una aplicación por separado para que "funcione" y, aún así, no logra su cometido.
Es así como, después de 10 años de tenerlo instalado por defecto, le digo adiós a esta extensión.
Muchas gracias a los desarrolladores que, en su momento, lograron mantener a flote este proyecto.
