RulesTab sample

Using the new IFiddlerExtension interface from Fiddler2, I've created a simple Rules tab that enables editing of your FiddlerScript script without running a separate program. 



  1. Download the and extract RulesTab.dll
  2. Place RulesTab.dll in your My Documents\Fiddler2\Scripts folder.

Source Excerpt

using System;
using System.Text;
using System.Windows.Forms;
using Fiddler;

[assembly: Fiddler.RequiredVersion("")]

namespace RulesTab
  public class RulesTab : IFiddlerExtension
    private TabPage oPage;
    private RuleEditor oEditor;

    public void OnLoad() {
      oPage = new TabPage("Rules");
      oEditor = new RuleEditor();
      oEditor.Dock = DockStyle.Fill;

    public void OnBeforeUnload(){}
