Pop-Up Exterminator - Version 1.2.0.90 The Pop-Up Exterminator prevents those pesky pop-up windows from appearing while you're surfing the web. Pop-up windows are quickly closed and don't have a chance to display their contents. The Pop-Up Exterminator can be temporarily disabled by holding down the CTRL key while a pop-up window appears. The Pop-Up Exterminator is very intelligent and customizable. By default, it closes all pop-up windows. This default behaviour can be overwritten. It also allows the user to setup rules that are applied to pop-up windows. Some rules can be used to allow or prevent all pop-up windows while visiting specific web sites or URL's. Other rules can be setup to allow or prevent popup windows that start with a specific URL while visiting any web site.
