PopupKiller eliminates popups and limit opened windows.

You can also limit the maximum number of opened windows. The program does not use and does not install external libraries.

While being installed and uninstalled it causes no problems with Windows. It works with Netscape Communicator and Netscape Navigator, Microsoft Internet Explorer, Mozilla, MSN Explorer.

It is still not tested with NeoPlanet but it is supposed to work with it too. As MDI (Multi Document Interface) is used in the Opera browser, Pop-up Cleaner cannot work with it.
