@netchami, yes, the same as I have in the Vivaldi adblocker, but this is a continuo game of Cat and Mouse and uBO need to be updated almost dayly if it want to work, because YT anti-adblocker do it too.
This script works different, YT don't even know that you watch the video with this, it's like a front-end in the same YT page.
I only use the Vivaldi adblocker and have installed the script as an extension (no need of TamperMonkey in Vivaldi) and I've never seen a nag, ad or other crap again in YT.
