This app is now totally useless with the latest Firefox 57. Do not waste your time installing it.
I have no idea why it post processes for an extraordinary length of time resulting with a QR stamp and asking to sign up for a license.
How can it take so long with the latest quad core i7 gaming computer?
I have now removed it. There are plenty of alternatives that work correctly.
It is a great shame because it used to be one of the best, which I had reviewed with 5 stars in the past.

Very complicated to use with all of these different options and functions, I just need a basic extension to download videos!

Re-encodes final video, consuming CPU while adding QR code in the corner of the video.
It's slow and thanks to re-encoding utterly useless.

Вы что натворили, разработчики? У меня Мазила 52 и выше не ставиться, а прога "Видео Даунлайд Хелпер" не поддерживается и не хочет устанавливаться... Чувствую надо переходить на другой браузер, как мне и советовали друзья...

Péssima! Demorada e não converte só perdi meu tempo e não consegui um suporte adequado!

je me sert depuis deux ou trois de dooland helper qui est un très bon logitiel ;que j'ai mis a jour il y a trois ou quatre mois

qui le rend encore plus facile d'utilisation...je vous le conseille

When you install this app look what it wants from you access to all your data, the list is endless. remove all these privacy violating features and this would be perfect.

It can't download blob video(EX:avgle).
Firefox 57.0(64 bit)

Video Downloader icon doesn't show in Firefox toolbar after downloading it so its useless to me.

c'est un scandale de demander de payer pour un logiciel gratuit

Message : appli compagnon non installé !! Que vient faire cette application ? Impossible de télécharger une vidé youtube.

Used to be 5 stars and a must have, used it everyday without fail....Since the update a few days ago its totally useless, would uninstall but I'm hoping you fix it..11.25.17

Nouvelle version nul.

worst

load of crap...nothing else

After the latest Firefox, download helper ceased to work

Requires a $30 USD license.

Does not work with firefox 57, latest beta (Version 7.0.1a3) is flagged by firefox57 as not being compatible

now I can't download some movie files which I used to be able to. disappointed.
