Panicware's Pop-Up Stopper blocks pop-up ads in Netscape, Internet Explorer, and Mozilla. It can block Messenger Service and desktop ads, too. There's no need to adjust proxy settings or add sites to a list. Pop-Up Stopper will not strip Web images or slow your browser. You can allow pop-up windows when you want them. User settings allow various pop-up notifications, such as flashing icons or new, fun sounds. Simply hold the Ctrl or Shift key to allow selective pop-up windows; but most new links should open automatically.
