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

Doesn't work anymore. No error message.

very slow download speed ,bad interface and factionality one of the worst app i have use for download

Non è più in grado di scaricare video senza l'installazione di addon aggiuntivo che però non è per firefox, ma si installa direttamente nel sistema. Non mi piace questa cosa, quindi ne sconsiglio l'installazione.

It is no longer able to download videos without installing an add-on, which is not for firefox, but installs directly on the system. I do not like this, so I do not recommend the installation.

Does not work (anymore?) with all web-video, and now makes Firefox freeze on an attempt for recapcha loading on a login-page...

Aplikace k hovnu!

asked to download a companion program on first download video attempt. I don't trust it, That's fishy stuff.

Always demand I add another extension which is not mentioned in Firefox explanation of this add-on. So, I don't trust. Their support page is blank.

Скурвился аддон. Требует "Companion App" устанавливать в ОС, без него не позволяет скачивать. Осталось только удалить.

Video downloader is unreliable. It is a janky piece of software that is not user friendly. It doesn't not download videos seamlessly. It's hit and miss. It fails. I cannot invest in or support software that performs this poorly.

Watermark on videos

It used to be free. Now it forces video conversion and if you don't pay, it watermarks your videos. DO NOT RECOMMEND.
