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.

I just wanted to download a 30-second YT video - even after installing the helper app, it took 10 minutes to "aggregate" then informed me it had watermarked the video because I chose an "ADP" menu option (the only one available) and didn't register some conversion feature. A huge waste of time for even the simplest of uses.

Ist nur noch ein standard downloader

The author describes the add-on as "The easy way". The first time i try to download and convert a YouTube video the add-on says i need to download additional software. The second time i try it tells me i need a license. The third time i try i uninstall the add-on and leave this review in a stern reminding of how you never can trust the words that an author uses for their own product.

Zuerst muss ich noch ein zweites Programm in Windows installieren, damit die Videos konvertiert werden, sonst kann ich den Download nicht ansehen. Danach muss ich trotzdem für ca. 20€ noch eine VideoKonvertierungsRegistrierung kaufen, weil das Video ein Wasserzeichen bekommen hat, was man sonst nicht weg bekommt.
Das geht mit einem anderen AddOn viel schneller, ohne alles! Und der Download und die Konvertierung geht ca. 10 mal schneller!
Keine Ahnung, warum dieses AddOn hier eine Firefox Empfehlung ist...

War früher mal gut - aber seit längerem funktioniert das Prog. bei mir nicht mehr.
