                browser.AllowNavigation = true;
                browser.Navigate("My URL");
                browser.Width = 1024;
                browser.Height = 768;

                browser.DocumentCompleted += new WebBrowserDocumentCompletedEventHandler(DocumentCompleted1);
                while (browser.ReadyState != WebBrowserReadyState.Complete)
                {
                    System.Windows.Forms.Application.DoEvents();
                }
            }
        });
        thread.SetApartmentState(ApartmentState.STA);
        thread.Start();
        thread.Join();

    }

Well, you're using the WebBrowser control which is built around the IE engine. You'll have to use something else to get another browser. Check out something like Awesomium.
