Adds an watermark and wants a donation for it to be removed so its straight up trash. Save yourself some time and do NOT DL this garbage. Just check out the creator Paul's website:
"I now run a software engineering company specialised in web engines."
This dude does not need your money. Greedy mf.

Now includes a huge watermark on videos. Deleted it.

Became useless, I am not paying 30 dollars for something that could be done for free. use a website or another extension instead of this junk of software.

Used to be amazing cause it downloads videos from nearly anywhere. But now it is a useless piece of rubbish! It leaves a huge QR code covering a big portion of the video which you have to pay $30 to remove. This is a new change. Do not bother with this rubbish; it is now a waste of time!

and please you developers make it how it was before...!...

No longer recommended. They add a massive watermark over half of the video and charge you $30 to remove it.

After downloading, it displays a QR code for half a video.

This extension is not free. Not only does it add a massive QR-Code watermark to your downloaded video without telling you, for some it also needs to install a local program on your device, very shady. Avoid.

Leaves a huge QR code covering a large chunk of the video, and does not tell you it is doing so until after a long download.

wastes your time and watermarks the video, not informing you until after download

the freakin QR? how about you warn me before I waste my time?

Kein Download möglich ohne die alleinstehende "App". Zeitverschwendung.

It's a scam. It may download files, but in formats it can't play. It demands money to convert them to a playable format :3

I simply downloaded the extension to install a youtube video as an mp3 file, easy enough. After opening the application and trying to do so, I was then prompted that I needed an external application to even do that... Okay, sure. I install the external application (which no other firefox extension has ever required from me?) and tried again to download the mp3. I was then prompted that I needed a $30.50 arbitrary subscription to do so?? I Was only told this AFTER I installed the third party application. That was annoying, but whatever. I decide to just download the video as an mp4 and manually get the audio I need, because seemingly just mp3 is a premium. I was then told AGAIN that I needed a subscription to do so as well??? This application does absolutely nothing unless you pay the author an exorbitant fee, which is never clearly disclosed to you. This extension is straight up predatory and dishonest as it doesn't make it CLEAR to the user that they 1. need an external application to do certain things and 2. doesnt up front tell you that you need to PAY to use it until you conveniently already have the application installed.

There are plenty of other free alternatives out there to do the same thing. Uninstalled.

It recently started blackmailing me to pay 20 euros otherwise a huge QR code covers like a quarter of the video. Totally useless now.

requieres external window downloader. Dosent proper work and requieres additional payments

Watermarks downloaded videos unless you pay 30.50 USD.

Did literally nothing for me

You are as greedy as all the other domains and services. What help are you, at all?

Required a $30.00 purchase for a "License" to download audio-only files.
