I'm glad VDH is working again. It wasn't working for a long time. There's just one problem. When a download fails, I can't refresh it (so that it picks up where it left off). Some other downloaders, especially with Google Chrome, pick up where the failed download stopped.
Please adjust your downloader so we can refresh our downloads when they fail.
Thank you kindly, in advance.

Companion application required! It even doesn't work on its own!

This requires an additional program to work. But what's worse, this add-on also puts a big ugly QRcode in the upper left of the video. The QRcode points you to the developer's webpage. While this might be alright for some people, it is not alright for others. Disclosing this information prior to downloading might have made me not waste time on this add-on and the required accompanying program.

Videos originate with a file, and that file is referenced on the webpage. This add-on takes a relatively simple task and makes it overly complicated. There are other options, this option is terrible. They have an overly complex conversion system that they obviously wasted a ton of time on. Most people won't use a conversion system, but for those who would use it, they certainly wouldn't put up with a video that has a huge ugly QR code in the corner...

My guess is that the only reason this add-on doesn't directly download any video file is that it "needs" to slap that QRcode in the corner... So they purposely add more complexity and complications in order to ruin the resulting video.

Mozilla really needs a better review process. ANY review that doesn't mention this QRcode or the required additional program is obviously a shill rating. Again, the problem isn't the existence of those two issues, it's that they don't tell you that they have those two issues (because they are undoubtedly issues of their own making) Not recommended.

Stinks

I have a Ryzen 7 and rendering a video took 99% of my cpu and it takes a lot, i mean wtf? are you mining or something?

Videos downloaded has QR code added. ¡Uninstalled!

La liste des sites supportés est énorme. Permet de récupérer facilement des vidéos a priori non téléchargeables, et pas seulement sur Youtube.

Worthless.

A VECES SE CUELGA CON LA NAVEGADOR, SINO ES VELOZ Y EFICIENTE

Too slow to download videos.

Horrible que no se pueda instalar en firefox esr

Always have a qr code on video downloaded now... toujours un qr code affiché sur les vidéos téléchargées maintenant...

не что не работает постоянно обновите как вы раньше работали

to make it work right I had to pay for it I got two other ones free. so they can bite me

Além de confuso, agora está colocando marca d'água.

too complex & hard to use, never works

Add-On erfordert die Installation von download Helper.
Die Videos werden zuerst heruntergeladen und dann konvertiert.
An sich wäre das ja nichts schlechtes jedoch verschwendet dieses Add On enorm viel Rechenleistung um einen QR-Code in das Video einzubetten. (20 min langes Video benötigt auf einem Xeon E3-1245 mit 16GB Ram bei 100% CPU Auslastung ca. 1 Stunde zum "Konvertieren") Der (riesige) QR Code wird im Video im linken oberen Bereich eingebettet. Folgt man dem im QR Code enthaltenen Link, so kommt man zu einer Seite wo man die Info erhält, dass für eine Version ohne QR Code Lizenzkosten (€18,50!!) anfallen.
Dieses Add On hat somit nur meine Zeit verschwendet!
