it doesn't work.

Requires some additional software to be installed. Shady AF.
Meanwhile extensions by other devs work perfectly as is and don't require additional bloatware.

IT DIDNT EVEN WORK ! ! !
internal file manager is disaster. How can I get it to use standard Windows manager ! ! !
doesn't do anything on Android ! ! !
completely useless ! ! !
Need external component, which i don't find reasonable ! ! !
This program sucks, the interface is total garbage, it installs a program on your computer that is suspiciously named : companion app
Difficult to remove and it has a massive paywall to prevent the videos from having a watermark on them.
This use to be a great add-on but is completely useless now ! ! !
The recently posted positive post have to be fake ! ! !
Adds a massive QR code that obscures the video being played. This is crappy adware ! ! !

Funciona estupendamente. Cumple su cometido y hay calidades de descarga para elegir.

Where other downloaders fail, this works. Simply the best.

A veces se desactiva o no baja los videos.

Ok

I use Linux 90% of the time and Windows 10 the other 10%. Video DownloadHelper is available for both operating systems. I tend to use Firefox for most of my browsing and Video DownloadHelper works well with both platforms. Most of the videos I download are for later reference. Having a video library of "how-to-dos" saves me a lot of time and frustration. This app works in the majority of sites I visit. I've tried other Firefox extensions to accomplish video downloading, but none even approach this one.

works great

One of the best and most useful add-on on Mozilla

This is one of those great add-ons that "just works." Easy to use and seems to download pretty much everything. Great app.

IT DIDNT EVEN WORK

Un module indispensable, facile d'utilisation et pourtant il offre beaucoup d'options.

非常优秀的软件，感谢作者的付出

Amazing, fast and easy program
