To gain control of all of the aspects of web activity such as ads, popups, web bugs and other annoyances, download for both Linux and Windows "Privoxy" at http://www.privoxy.org . Successor to the junkbuster program, Privoxy now comes with a configurable default.actions file which you can do yourself or key in http://config.privoxy.org once you have installed and the program is running. It offers an edit or three levels of default protection saving you the trouble of reading all those docs as thoroughly as you should.
