Perfect. One site was trying to force me to allow notifications with an overlay. Can't say how happy I am to give them the New York salute.

I use it every time I'm online. There're more and more sites that smack you in the face with some sign-up crap, and this effectively wipes them all away--either with a simple mouse click or an even quicker Cntl-Shft-X. Smack! Gone! The way is now clear.

This extension just simply works. And it has a keystroke combination too (Ctrl-Shft-X). I don't know why webmasters think it's a good idea to rudely interrupt you with a stupid, pointless overlay when you're on a mission and are totally focused on something else, but this extension is the way to fight back. Many thanks to the author!
