Unsuccessful to use Marionette, the next generation of FirefoxDriver

According to this Mozilla Developer Network, there is no FirefoxDriver from Firefox 47, instead we use Marionette.

I followed the instructions in this link, but it doesn't work as expected. I am using Java, Firefox 47 and Mac OSX Capitan

  1. I installed selenium driver with this npm install selenium-webdriver as suggested in the link
  2. I set up the Marionette executable by downloading this file geckodriver-0.8.0-OSX.gz, unrar it, and changed the name to wires as instructed in the link. And I ensured it is executable with chmod +x wires

  3. I used Marionette like this, from Mozilla Developer

    DesiredCapabilities capabilities = DesiredCapabilities.firefox();
capabilities.setCapability("marionette", true);

Webdriver driver = new FirefoxDriver(capabilities);

But when I run the test, the same exception like this normal FirefoxFriver

org.openqa.selenium.firefox.NotConnectedException: Unable to connect to host 127.0.0.1 on port 7055 after 45000 ms.

Is anyone successful to use Marionette? Am I missing something from Mozilla's instructions. Thanks

Solution

  • I had the same problem and just solved it by updating the Selenium version to 2.53.1.

    Hope it helps!
