I want an ad blocker, for popups anyway, that creates a second tab which emulates everything on the first tab, EXCEPT the popups. The user watches the popup-free second tab, while the website allows full access to its content, because the browser (truthfully) reports that it is displaying 100% of the website’s ad content on the first tab.
Would not work for ads like YouTube’s, that interrupt the entire content stream, but it would be great for popups.
Maybe I should have patented that idea, before posting it.
