Customize Menus

To customize menus in Fiddler, add rules using FiddlerScript with Global scope. For example:

Add context-menu item to open currently selected URLs using Firefox

	public static ContextAction("Open in Firefox")
	function DoOpenInIE(oSessions: Fiddler.Session[]){ 
	  if (null == oSessions){
		MessageBox.Show("Please choose at least 1 session."); return;
	  }

	  for (var x = 0; x < oSessions.Length; x++){
		System.Diagnostics.Process.Start("firefox.exe", oSessions[x].url);
	  }
	}

Add a submenu to the Rules menu and create an option in it

	public static RulesOption("Non-Exclusive-Test", "User-Agent") 
	var m_UANONRad: boolean = true; 

To build submenus with mutually exclusive radio options

	public static RulesOption("Spoof Netscape &3.0", "User-Agent", true) 
	var m_NS3: boolean = false; 

	public static RulesOption("Spoof IE &6.0", "User-Agent", true) 
	var m_IE6: boolean = false; 

	public static RulesOption("Spoof nothing", "User-Agent", true) 
	var m_UANONE: boolean = true;

To build a submenu with mutually exclusive radio options, that control a single string variable (Offers a more compact syntax than the previous alternative)

	RulesString("&SubMenuName", true) 
	RulesStringValue(0,"Option1Name", "Option1Value")
	RulesStringValue(1,"Option2Name", "Option2Value")
	RulesStringValue(2,"&Custom...", "%CUSTOM%")
	public static var sTheOptionValue: String = null;

Same as previous, but with a default option pre-selected

	RulesString("&SubMenuName", true) 
	RulesStringValue(0,"Option1Name", "Option1Value")
	RulesStringValue(1,"Option2NameDEFAULT", "DefaultVal", true)
	RulesStringValue(2,"&Custom...", "%CUSTOM%")
	public static var sTheOptionValue: String = null;

Add a Tools menu option that resets the script

	// Force a manual reload of the script file. Resets all
	// RulesOption variables to their defaults.
	public static ToolsAction("Reset Script")
	function DoManualReload(){ 
		FiddlerObject.ReloadScript();
	}

Add a Tools menu option that clears all WinINET/IE cookies and cache files

	public static ToolsAction("Reset IE"){
	  FiddlerObject.UI.actClearWinINETCache();
	  FiddlerObject.UI.actClearWinINETCookies(); 
	}
