To prevent the privoxy service from automatically starting when your computer starts up, remove or rename
the file /Library/LaunchDaemons/org.ijbswa.privoxy.plist (on OS X 10.5 and higher) or
the folder named /Library/StartupItems/Privoxy (on OS X 10.4 'Tiger'). To manually start or stop the privoxy service, use the Privoxy Utility for Mac OS X (also part of the
macsetup module).
