works

Very good. it actually works. Without additional external files or extensions to windows explorer or other types of bugware/crapware that "need" to be installed alongside the extension. I like that it offers options for the available media types. Just like flashgot used to work on older versions of firefox. Very good, thank you guys.

il télécharge les 1080p avec sons, très bien avec la nouvelle norme de google (youtube), et aussi facile à utilisé que n'importe quel autres anciens bon app pour youtube, fin novembre 2021

I have AVG antivirus installed on my computer and I do not know if it is due to AVG but I could not download the 4K file at https://www.youtube.com/watch?v=LarDrhbO7b0
even after allowing the download to proceed.

Here is what AVG says:
Threat secured
We've safely aborted connection on s5.youtube4kdownloader.com because it was infected with URL:Malvertising

I am very disappointed!

To answer the developer:
The big problem is that, with AVG installed, I cannot even reach the stage where I can download a video file through this addon because AVG does not allow me to do so and AVG does not even allow me to override their blockage of the downloaded file in any way.

yeah working great with 4K resolution

Works perfectly ! Download video in HD, also download audio ..., then you have to marry both tracks with a suitable program. Firefox version is: V 92 (64-bit) - for Windows. It also works well on Ubuntu 20.04 LTS.

efficace et simple

It works! Very few work, but this one does.

yep thanks works good

still cant use this to download unlisted/privated/restricted video but other than that i can download any other normal vid
