This no-nonsense pop-up blocker blocks pop-ups and pop-unders when you're surfing with Internet Explorer. It blocks pop-ups before they are downloaded by your browser, and you can easily turn the application on and off. This program is completely mouse-operated. FiveStar PopUp Blocker keeps two lists, the Green List and the Red List. Put a site on the Green List if you frequently visit it and want to allow pop-ups. Put a site on the Red List if it generates pop-ups. It's easy to switch the status of a site from Red List to Green List or vice versa. Get a star each time a pop-up is blocked and see how many stars you've accumulated each month. The more stars you have, the less attention you pay to annoying pop-up messages.
