This extension should be supported by Firefox because this extension is the #1 reason for using the Firefox browser.
IF YOU OWN A COMPUTER, YOU NEED THIS EXTENSION!
Without this extension, I could be a productive member of society instead of downloading everything I can get my fingers on, endlessly filling up hard drives with downloads that I don't have time to watch because I'm too busy looking for something new to download!
If this developer ever dies, the internet will die with him!
OK, it isn't perfect. Nothing is. Every time THE MAN changes the way they stream, this developer springs into action to fix, adapt, and get things back on track.
I especially like that Facebook now works, where I used to have to go to another site in a 3-step process to convert to a downloadable format.
And I can't say that I'm thrilled with the new interface, but I'm getting used to it and it's much easier to adjust to than going from MSO to LibreOffice.
Every time I have problems, I just wait a couple of days and it gets fixed.
This is literally the BEST video downloader in history!

appréciable pour enregistrer des moments et des musiques introuvables dans le commerce.

É uma de minhas extensões favoritas. Ótimos recursos e eficiente. Recomendado 100%!

Video Download Helper is my favorite add-on. I paid a small amount for the lifetime premium license for Firefox and it's been worth every penny. For the most part, VDH has worked flawlessly and it has enabled me to build a video library of performances and interviews from my areas of interest without tracking or annoying ads. Highly recommended!

Works almost all the time unless the video is DRM protected, which makes sense.

Muito bem, funciona mesmo é só instalar os plugins necessário e pronto.

depuis la mise à jour de décembre l'app détecte les vidéos mais il est impossible de les télécharger, il y a toujours une erreur. j'ai essayé en navigation privée ou non, en mode j'accepte tous les cookies ou non, avec le plus de confidentialité ou avec zéro, elle ne fonctionne jamais. scandaleux

works really good, thank you so much

The best. Downloading the subtitles with the videos would be nice, tho.

Still, the best :D

Excelente!! Fácil de usar

It's works GREAT

I've found this to be the most reliable downloader. It works where others don't - rarely fails. So easy to use. Serves me well.

Ich bin super zufrieden mit dem Download-Helper. Dadurch konnte ich schon viel Wertvolles für meinen Hausgebrauch absichern.

literally works exactly as intended! for all sorts of websites!

A bit contentious with Youtube (sometimes it works, sometimes it doesn't, though with how stingy Youtube is that's hardly surprising) but overall the only extension you'll need for downloading videos from all sorts of places and all sorts of players. Highly recommend if you're interested in preserving, well, Anything, especially with how gatekeep-y the Web has become.

ITS SO PEAK
Simply lovely, easily a top 10 human creation

Fantastic extension, easy to use. Wish I heard about it a long time ago

Video DownloadHelper is a very useful tool for my needs, and I highly recommend it. There are a few situations where I can’t always download videos—I’m not sure why. That’s why I’m giving it only 4 stars.

I love this app as it is a very simple straightforward extention. A few rare times it stops working for unknown reasons but it's still one of the best
