Popup Inspector - Version 1.1 The #1 Rated Popup blocking software available. Popup Inspector's intelligent Popup Inspection Engine can block 100% of annoying pop-up and pop-under ads without interfering with your web surfing. Unlike most pop-up killers, it works without human intervention; and there's no need for adding lists of blocked windows, or allowed windows. It only blocks unsolicited pop-up windows without in any way interfering with opening new windows! The PopUp Inspector blocks PopUps BEFORE they can even start to download. This prevents pop-up and pop-under ads from stealing bandwidth or locking up your browser with multiple windows opening.
