This plugin gets the job done.

I've been using an add-on called Video Downloader Help for quite a while now and I thought it might be helpful to let others out there in cyberland know what an invaluable asset it's been to me. All my previous Video download tools persistently let me down and caused me no end of frustration. This little bag of tricks always seemed to be on my side in heliping to avoid all the technical and procedural mishaps that can occcur when downloading.
What I always find especially reassuring is the way the very convenient interface allows you to pick and select your preferred formats and quality of playback in custom-mode, as well as a facility for monitoring the rate of progress of your download. Thoroughly recommended as an Add-on For Everybody.

Still awesome !!!

Screw this addon for forced conversion of videos in order to add that stupid ugly ass QR code in them. My CPU overheated because of the conversion load and my notebook restarted because of that. As a result I lost some data I was working on.
F.U.C.K. you the author of this piece of sh1t.

Useful addon.

I have been using Video DownloadHelper since 2009!
It worked PERFECT then and every update since has made it BETTER!
It is without a doubt, the BEST Add-on I have EVER USED!

Die beste App

AWESOME!
I always used to get pissed whenever I couldn't download the right version of a song I want. Now I don't.
Highly recommended with YouTube.

Mto ruim....baixar algo no youtube na versao free reencode o arquivo com uma marca d'agua ate ai blz....+ 4horas fala serio

Did not work. Running Firefox 60.4.0esr (64-bit). Attempted twice to download a 90 minute video from YouTube. According to NetWorx, VDH downloaded all 1700 megabytes of the MP4, but after the download was completed, all that was in the download folder was a 100 mB clip with only a few seconds of the beginning of the video. And it was not in the folder that I had specified in Settings. A search of the hard drive failed to uncover just where the app had placed the 1700 mB data stream while it was downloading, so I assume the app erased it. Removed this extension, I'll have to try and find something else.

Does not work, and want's to install other nasty Stuff

Thanks for this program. It's the best one I've ever used

estupenda aplicación!
