Always wanted me to download its companion app, what's the point of having the extension if it needs an another tool anyways?

Расширение требует установку стороннего приложение, которое не проходит проверку в firefox. Так приложение модицифирует скачанное видео, т.е. вы получите не тот виде, что вы хотели.

1) You need to pay to get rid of the QR code

2)Not straightforward with the options

Unfortunately, this add-on is just another trick to get you to install third-party software (an "additional helping program") of unknown provenance, whose security threat is unknown. I tried it with a Yahoo video only to find it would not work unless I added their special program.

not work

Langsamer Download, Zusatzanwendung erforderlich, Bedienung unübersichtlich, Heruntergeladene Videos sind in der nicht-registrierten Version durch ein Wasserzeichen (QR-Code) zerstört und unbrauchbar. Wasserzeichen lässt sich nur durch eine kostenpflichtige Registrierung entfernen.
Ein absolutes No-go!!!
Dieses Addon habe ich direkt wieder entfernt.

The program does not work on Ubuntu. (Ubuntu 21.10.) The program is installed, but when I try to download it, it displays the error message that a co-application is needed, as if I hadn't downloaded it. Absolutely not usable. Has the developer ever tried this on Linux? Earlier versions worked without further ado.

Started watermarking + charges $30USD to remove, until then was very good

Edit: Use jdownloader2 or youtube-dl + tartube/stacher [gui for youtube-dl]

Existem outros meios para conseguir doações. Essa marca d'água ficou horrível e os downloads ficam muito mais lentos.

Super annoying site. No download link.

Used to be a free and mediocre extension. Now it adds a watermark. Scummy practice making a useless extension.

stupid watermark, probably the worst video downloader I've found so far.

Gives you a big ole QR watermark now. Nooooope!

Os downloads estão demorando muito pra completar, depois dessa atualização que coloca o QR code a extensão piorou demais.

No funciona con regularidad, no guarda dónde le indico, no puedo programar sus funciones como antes

A great downloader Rarely Fails & quick to save videos recommended try it & see .

Extremely slow, requires a companion app now, very clunky UI and also adds a watermark to the videos. This addon used to be so much better, what a shame

VDH used to work fine, but now it just says "Companion App not installed". So I downloaded the .deb file (I'm on Ubuntu) and installed it. It puts the binary in /opt/net.downloadhelper.coapp/. But still it says "Companion App not installed". So how does it find the binary? It's supposed to look for a .json file, which the .deb file installs in /usr/lib/mozilla/native-messaging-hosts. But wait, Firefox is a 64-bit program, not a 32-bit one (we're in the 21-century now!) so it should be in /usr/lib64, not /usr/lib. So I make a symlink from the lib dir to the lib64 dir. Still doesn't work: "Companion App not installed." :-( I'm giving up since it's already taken a lot of time to discover these bugs. I suspect that it's a minor configuration problem that failed QC. It's probably simple, but it's enough to keep VDH from working at all.

Puts a WATERMARK on your video, but doesn't tell you until after it's done converting. And the converting takes a ridiculously long time because they're RE-ENCODING YOUR VIDEO to put their stupid QR code watermark on it!
