Nearly a billion users worldwide use Ad blockers when they peruse the internet. These usually come in the form of extensions to the user’s browser of choice, and they remove any advertisements in whatever form they take (pop-ups, video embeds, banners, etc.) That being said, what is Ad blocking, and how do these extensions work?
