The world’s smarmiest advertisers have begun inundating us with pop-up
and pop-under ads—nasty little windows that appear in front of the browser
window, or, worse, behind it, waiting to jump out the moment you close your
window. They’re often deceptive, masquerading as error messages or dialog

them. It’s a war out there—but at least you now have some ammunition.
