very very very very very very to the power 100000000 FRACKING SLOWWWWWW come on with the order already!!!!

Внезапно стало требовать установки непонятной внешней программы. Отличный способ впарить майнер или рекламную малварь.

adds watermark unless you pay... I'm now enjoying XDM Browser Monitor and it works for both Firefox and Chrome even up to 4k it also catches other downloads

Used it once. Put a 25% watermark on the video and demand I pay money to avoid that again in the future. Immediately uninstalled and back to using web services.

Most videos require an extra software to be installed on your computer, what the developer calls a "companion app", even though it should not be necessary since a simple video grab is clearly within the web browsers ability.

wouldn't work at all

no good

now in 2024 it's been tampered with and doesn't work at all. Complete waste of time.

Technically, this is a very good downloader, the trouble is that when it comes to practicality, the free version becomes pretty useless as the makers have ensured that for the videos most people want to download -notably anything Pop-music related- are usually ADP -meaning they have a large watermark- or are so low quality that they're not worth doing. In short, a fundamentally mean-spirited sprat to catch a mackerel -I'd recommend instead using downloaders such as Ant that are more generous with what they allow.

no longer free

Полное говно, тупит, добавляет штрих код в видео.

I have been using this Add-On, on and off for years now, but for some reason, you now need a app companion to download the videos, I am sad to see this app go, but i am not willing to pay $28.50 USD to download a few videos from time to time! thank you for the great Add-On, sorry you ruined it with that extra companion app.

Previously it was of great value but now you just download and install after that it doesn't work. Waste addon!

Memory leak on Youtube Live

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.

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
