Expected:
The sample script should be passed in Firefox also.



Note:
Anyone please provide the solution to solve this issue asap..
Now i cant able to run any script using Firefox browser,the same error getting displayed.

Please check your network settings to ensure there is no proxy or firewall blocking
or redirecting connections to localhost:7054

The same issue is reproduced on my desk (Windows 7, 64-bit) when I run Selenium test
cases by multi thread (DforkCnt=4). This issue appears randomly.
I checked the network by "netstat -an" and 7054 port is not visible there.
I killed the "firefox.exe" from  task Manager and the tests start to go.
Did you find a solution how to avoid this problem while running the test cases in multi
thread?

below is the stacktrace from my command line:

Hello, 

I'm facing the same error with FF 36.0.4 and WebDriver 2.45.
I get it when I'm trying to open a new instance of Firefox.

This is my code:
WebDriver browser1 = new FirefoxDriver();
browser1.get("http://google.com");
WebDriver browser2 = new FirefoxDriver();
browser2.get("http://yahoo.com");   

And this is what I get in the console:
