Popups. They're baaaack! Half the websites out there seem to have decided (roughly all at the same time) that full width toolbars or promotional bars that rise up at screen bottom and cover up content, or slide-in promotional boxes that obtrude themselves from screen lower left or lower right or both and cover up content, are absolutely wonderful ideas. Ad-blockers don't seem to think they're ads since what they're flacking for is the same site you're already on (The VERY NEXT New York Times story you'll want to read is...) rather than something in a different domain. Is there any hope of blocking these? Thanks very much!
