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!

I don't know how VDH did it, but they retroactively put a bunch of watermarks over all the videos I downloaded. Probably their "companion app" ran in the background while I was doing something else, and re-encoded everything with a stupid QR code watermark. So now I have a few gigabytes of video with a QR code asking me to pay $16 to remove the QR code watermark. This is no better than ransomware, and if you're smart you'll avoid this app and report it for abuse.

It did used to be a 4.5* app, these changes are recent.

Very slow conversion. It stopped working with youtube.

Useless extension due to watermark.

Maybe it's me as I realize that my skills in this area may not be comprehensive enough to use this extension but I installed it with no problem. Then I tried it and it said I needed a companion app and gave me two options for that. I tried both options, even having to tweak my security settings to allow the .pkg file extension. Then it finally allowed me to choose the format/conversion except being a laymen there are so many options that seamed so similar like mp4 1mb vs mp4 2mb. So by one I tried the ones I recognized as to not overload/overburden my macbook or the server or whatever can get overloaded. None of the formats, not even one actually downloaded. I gave up, tried another similar extension. One click to download the extension, then one click to select the format then a third and final click to download the media. That's it! The other one worked. Maybe this extension is simply too sophisticated for my average/adequate skills. I'm assuming it's me but maybe this review will help developers think about us laymen when creating extensions in the future. Cheers!

Spyware. VDH asks you to install an app. DON'T DO This. Your IP address is changed and rerouted to a bot with IP 37.1.188.237, located in Manila, the Philippines, GPS location 14.61 120.97. Various sites will refuse entry, telling you you're on a bot and at an abnormal location. Some virusscanners know this and act.I you are on Linux and have Redshift: the color temperature of your screen will give the time and temperature of the Philippines. To search a nearest shop location (entering postal code): doesn't work anymore. In case you have installed that app: only switch VDH on when needed and switch off after use, but never start your computer with VDH switched on. Or remove VDH and reinstall without the app? I'm not sure if the app is removed together with VDH.

made youtube videos unplayable

Allows you to download ONCE and then every video afterward will require you to install a third party application - even if you go to download the same video again, demonstrating that it's not just a certain type of video that requires the "companion application"

This screams malware.
