Just and idea for hack. You may use Reflection methods to get process of firefox instance. First declare FirefoxDriverEx class inherited from FirefoxDriver - to access protected Binary property which encapsulates Process instance:

 class FirefoxDriverEx : FirefoxDriver {
        public Process GetFirefoxProcess() {
            var fi = typeof(FirefoxBinary).GetField("process", BindingFlags.NonPublic | BindingFlags.Instance);
            return fi.GetValue(this.Binary) as Process;
        }
    }

Than you may get process instance for access to MainWindowHandle property

using (var driver = new FirefoxDriverEx()) {
            driver.Navigate().GoToUrl(url);

            var process = driver.GetFirefoxProcess();
            if (process != null) {
                var screenCapture = new ScreenCapture();
                var image = screenCapture.CaptureWindow(process.MainWindowHandle);
                // ...
            }
        }
