@wibrst, I still block ads in YT, but without these nags, but instead of the Vivaldi adblocker, which in YT now only block trackers, I use the Violentmonkey extension with these scripts.

You can install the userscripts also directly as extension, downloading these in a folder and drag these in the extension page in developer mode, but then you must these than update by hand, in the Violentmonkey extension theu are linked direct from the Greasyfork site and not from your HD.
