Pop-Down is a program designed for Internet Explorer. While enabled, popup windows will never interfere with your web surfing again. Popups are killed before they are created, so you will never see them, nor download any of their content.
Pop-Down will notify you each time it kills a popup, so if it kills one you wanted, simply depress the Ctrl key while the popup is being created, and it will not be killed.
NEW! Version 2.0 does not prevent you from running Internet Explorer directly, allows you to choose between beeping the PC speaker or playing a custom wave file, allows you to block Web Page Dialogs, and is hundreds of times faster than it's predecessor. Written in pure C, so it's tiny, fast, and has no dependencies. No install required, just unzip and run. Includes context sensitive help.
