Complete JUNK. NOT, NOT, NOT working!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

I tried the 4K online clipping site.
Whatever Youtube video I uploaded, whatever mp4 resolution I tried to download, whatever vpn country, it returned error "try another download link".
Make it work or stop wasting peoples time and take it down.

Значок не реагирует вообще ни на что

This module is not at all up to date and works very poorly.
Very often it does not detect the video link and returns the following error message :

"An error occurred from remote video site. Please try with other download link."

When you get this then you can choose another format, and if by chance it finds the link the audio is in German !!!!!
There, to understand something, hello anguish.
And since no clear explanation is available I do not know what to do.
I give up on that, there are others that work.
I absolutely want to keep the original language of the video and especially not translate anything because the translation systems are not yet up to date. Maybe in 50 years it will work better ?

не работает

Tested just now with an age restricted download on youtube and it says An error occurred from remote video site. Please try with other download link.

so needless to say if you can fix that update I'd instantly rate 5. It also doesn't work on private downloader. There's no such thing as terms and conditions on youtube when they are impossible to enforce. Other programs can do it why not this?

Clicking download just brings me to a white screen. Gay.

Не работает

Siempre pone que no se puede conectar

Ha ocurrido un error al conectar con youtube4kdownloader.com.

El sitio podría estar no disponible temporalmente o demasiado ocupado. Vuelva a intentarlo en unos momentos.

The user interface of this extension works excellently, but this is of no use if the conversion page is displayed as white as snow. I am using the latest version of Firefox, so this cannot be my fault.

Doesn't work anymore. I always get the "An error occurred from remote video site. Please try with other download link." message.

wants money for normal quality downloads

Simple scam, that's it.
NO 4k download of 4k videos. Plus, even if you want to download anything above 720p you have to pay for the premium edition of this add-on. Which then the add-on no even works within itself but redirects you to all kind of pages.
F these Scammers, making money of the work of others

Downloaded the video twice, but there is no sound!
Update 2025: does not download at all!
