nice tool to download videos from youtube, really helpful for students ....Keep it up

fa bene il suo lavoro quasi mai senza problemi

-Uma porcaria,A última versão executada no Firefox Quantum (57) ,já não detecta vídeos que são reproduzidos em vários sites o Downloadhelper parou de funcionar,não baixa mais os videos que eu baixava antes!

Este programa es buenisimo

Please correspond to 4sync.com

Yesss you're back! \(;0;)/ I've missed your add-on!

Is the best!!

Used to work but now it's nothing but an elaborate scam, trying to profit from open source software. Should be banned from Firefox!

Love it

STARTING TODAY....TOTALLY USELESS
CAN NOT DOWNLOAD MP4

I CAN SEE THAT MANY IN THIS FORUM AGREE WITH ME.

VERY SAD.... IT USED TO BE THE BEST PROGRAM ON THE INTERNET.

I WILL LOOK FOR ANOTHER DOWNLOAD WEBSITE TODAY
AND CHECK BACK IN A FEW DAYS
TO SEE IF YOU FIXED THE PROBLEMS.

it wont pick up mp4 files in many sites it use to work perfectly before the update

The latest version running in Firefox Quantum (57) no longer detects videos playing on many sites - the icon stays greyed out :(

Great app if 60% of all videos did not require a paid companion app to go along with it.

best video downloader ive used, been using this app for years. everything i download is free, i don't know what these other people are talking about the companion app. i use the free version and it works perfectly. quick updates. 5 stars!
edit: having problems since firefox update? download older versions of both firefox and videodownloadhelper, seems to do the trick

Саиое лучшее расширение !!!

I have tried this addon for Youtube. It works for 720p videos. But to download 1080p video, you need a separate companion app. Because for 1080p, Youtube uses separate streaming for audio and video. But to download 1080p without any watermark, you need license. Otherwise, you will see a large QR code image in your downloaded video. It should be clearly specified in the addon description.

uma porcaria

I used to love this add-on, but since the upgrade for Firefox 57 it's completely useless to me. Don't think much of the Firefox upgrade either.

Ecco alcuni dei siti in cui DH funzionava perfettamente e in cui ora, a causa della vostra incompetenza, non funzionano più:
- http://www.seriehd.me
- http://altadefinizione.pink/
- http://www.altadefinizione01.love

avete peggiorato un prodotto che era eccellente.
Siete pazzi?

after upgrade firefox 57 this addons be useless
