    System.setProperty("webdriver.gecko.driver", "C:\\selenium\\geckodriver-v0.23.0-win64\\geckodriver.exe");


    DesiredCapabilities capabilities = new DesiredCapabilities();

    capabilities = DesiredCapabilities.firefox();
    capabilities.setBrowserName("firefox");
    capabilities.setVersion("31.0");
    capabilities.setPlatform(Platform.WIN10);
    capabilities.setCapability("marionette", false);

   // firefoxOptions = new FirefoxOptions(); 
    //firefoxOptions.setCapability("marionette", false);

    WebDriver d1 = new FirefoxDriver(capabilities);


    //WebDriver d1 = new FirefoxDriver();
    d1.get("www.google.com");
