When I run web driver with Firefox browser it generates a blank Firefox browser and after a minute the browser closes without running the WebDriver program. The following error is generated on eclipse:

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

Please how do I resolve this. I am using the latest Firefox browser (47.0.1), and selenium java client driver 2.53.0.

As of v2.51.0, the firefox driver supports Firefox 44, so without posting any code that's about all I can help you with.
