Question: I am getting error while using Firefox with WebDriver.

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

```

* Firefox version:47.0
* Selenium:2.53.0
* Windows 10 64 bit

Is anyone getting a similar issue or any idea what is the solution for this? It's working fine with Chrome but with Firefox none of the URLs are getting loaded.

Answer: 
Firefox 47.0 stopped working with Webdriver.

Easiest solution is to switch to Firefox 47.0.1 and Webdriver 2.53.1. This combination again works. In fact, restoring Webdriver compatibility was the main reason behind the 47.0.1 release, according to <https://www.mozilla.org/en-US/firefox/47.0.1/releasenotes/>.
I can confirm that `selenium 2.53.6` works with `firefox 44` for me on ubuntu 15.
