Debug tip for ASP.NET MVC 3 in mobile context

For manage Mobile page, I'm inspired from this excellent post "A Better ASP.NET MVC Mobile Device Capabilities ViewEngine" by Scott Hanselmann
But, when I want inspect some html parts or if I want trace a javascript behavior, I want and I prefer use Firefox and FireBug.
So, I create a fake mobile engine which use Firefoxe+firebug

First, I have added my new engine in globlal.asax.cs 
In "Global.asax.cs" (full source here)
protected void Application_Start()
{
  AjaxHelper.GlobalizationScriptPath =
  "http://ajax.microsoft.com/ajax/4.0/1/globalization/";
  AreaRegistration.RegisterAllAreas();
  RegisterGlobalFilters(GlobalFilters.Filters);
  RegisterRoutes(RouteTable.Routes);

  // Add the auto mobile detection & redirection
  ViewEngines.Engines.Clear();
  ViewEngines.Engines.AddIPhone<RazorViewEngine>();
  ViewEngines.Engines.AddWindowsMobile<RazorViewEngine>();
  ViewEngines.Engines.AddGenericMobile<RazorViewEngine>();
#if DEBUG
// Just use it for debug JS in firebug & inspect HTML
  ViewEngines.Engines.AddFireBug<RazorViewEngine>();
#endif
  // Std engine
  ViewEngines.Engines.Add(new RazorViewEngine());} 

Second, I had in my custom mobile engine my new "Firefox+firebug" fake mobile engine

in CustomMobileViewEngine cs (full source here)

public static class MobileHelpers
{
    ...
    //Add firefox + firebug for help to debug
    public static void AddFireBug(this ViewEngineCollection ves) 
                  where T : IViewEngine, new()
    {
        ves.Add(new CustomMobileViewEngine(c =>
                c.UserAgentContains("firefox"), "Mobile",
                new T()));
    }
} 
You could do the same thing with "F12" on IE if you are used it.
