Yeah.

I used to dive into the console and start removing stuff and even went so far as to write a bookmarklet that tries to identify and nuke anything with fixed position and reset the height to auto on body/html but ... if someone's going to be that user hostile it's not worth my time.

When this happens I'll copy the url, close the tab and paste it into archive.is.

same here. I don't even get mad anymore, just instantly close the page. This includes the cookie popup as well on mobile.

I tried this method, but i'm finding it impossible to book movie tickets when I keep closing the window on their homepage.
