This used to be a great tool for long time for me but then the developer decided to watermark downloaded videos with an annoying QR code which cover a quarter of the screen at the left bottom of the video.

No idea why it was necessary to do so. You could have easily invented a pro plan which would allow users to download videos of more length or higher quality, but you decided to watermark even the tiniest downloads.

Since then this tool become unable to be used for me sadly. I was lucky enough to find an alternative (which however does not work as smooth as VDH used to be), but at least does not force me to go through a decent paywall.

Yes, you can not spent your work for free and you have costs with this, I understand this, but there are other options generate money with your app or at least made the watermark a bit less big and maybe transparent.

You don't have to say "Okay, I'm going to force users to pay for it".

And as a sidenote, 18,50€ is way too much (even for a lifetime license). I would have spent 6/7€ for it, but not 18,50€. That sum even exceeds some AAA games revenue on Steam! Too greedy sadly.

Again, this used to be an excellent tool for a long time for me. It still detects HLS streams where other extensions simply fail to detect anything at all. Only could recommend it and gave it 5 stars, but with this policy change now, I cannot longer use nor recommend this extension.

I gave 2 stars because of functionality it provided for me once. But I would like to give 0 stars for the recent change to set an annoying QR code watermark.
