After I paid for the license, the key suddenly disappeared and doesn't work.
No serious response from support.

The first few videos, there was no QR code, and then there was a QR code after which takes you to a place to pay. There is no option to use PayPal, and I don't feel comfortable purchasing the conversion license without it. Then on the website, it says that there's no water mark on videos when there is, and it's big and gets in the way. This leaves a lot to be desired, and as soon as I find an alternative, I'm gone.

Sketchy additional installer required, no thank you.

Several years ago this was one of my favorite add-ons.
It would download music,video, and images with no problems. I used it a lot.
Now it won't download a lot of Youtube videos, some streaming video, or any images. When it does work it leaves a water mark or some kind of box on the video. It's slow, even slower to aggregate the video and audio to make another worthless water marked video. To get rid of the mark. you have to pay this pirate for a license. I am not going to pay for this add-on that doesn't work nearly as well as it did in the past. There are better video downloaders that are free with unmarked downloaded video. Try Open Video Downloader. Google it, don't pay the pirate.

Sadly, VDH is now plastering a large QR code in the bottom left of the video, obscuring much of it. :(

it requires to install other software, which is shady. no, F that. why would i need to install another software to be able to download. this is crap.

Used to work amazingly, now that put a huge watermark on every video unless you pay. Lifetime license is absurdly high. Very greedy.

The latest update does not work in Firefox Linux. I have installed coapp-v2 as requested by this version, but it still does not allow me to download anything. Will this be fixed someday, or will I have to switch to another video downloader?

giant qr code in the corner of all videos downloaded

Adds a GIANT QR code to the downloaded video unless you pay 20€. NOT WORTH IT

В последнее время приложение не работает, пишет Download failed. Sadly we failed at downloading that specific media.

You want $30 for software that doesn't do the job it advertises? That's egregious.

Vergognoso: ti costringe ad installare una componente esterna e poi, quando salva, piazza un QR code che copre quasi metà del video. A meno che non paghi 20 dollari. Le recensioni a 5 stelle sono sicuramente tutte finte.

All of the sudden this dev wants $30 to continue using this app, otherwise you get a very obnoxious QR code taking over the downloaded video.

Not working i only need a working download url but no...

Author slaps huge QR code in videos, making the download useless. 1 star till removed.

You need to pay to use this otherwise you get a giant watermark QR code in your video. Lame that the author thinks it's okay to make money from copyright theft.

The author purely decided to shake money from people with his giant QR code! One star and I hope that he will be blocked for such arrogance!

Has now added a giant QR code that you have to pay to remove. It never did this until recently. Website says it has done this since 2006 or something silly but this is not true. Reported to Mozilla extensions people.
