Firefox WebDriver doesn't work with Firefox 32

Question

I've just updated to Firefox 32, when I attempt to run my Selenium Webdriver Test, Im getting the following

Failed to start up socket within 45000 ms. Attempted to connect to the following addresses: 127.0.0.1:7055 OpenQA.Selenium.WebDriverException was unhandled by user code   HResult=-2146233088   Message=Failed to start up socket within 45000 ms. Attempted to connect to the following addresses: 127.0.0.1:7055   Source=WebDriver   StackTrace:        at OpenQA.Selenium.Firefox.FirefoxDriverServer.ConnectToBrowser(TimeSpan timeToWait)        at OpenQA.Selenium.Firefox.FirefoxDriverServer.Start()        at OpenQA.Selenium.Firefox.FirefoxDriverCommandExecutor.Execute(Command commandToExecute)        at OpenQA.Selenium.Remote.RemoteWebDriver.Execute(String driverCommandToExecute, Dictionary`2 parameters)        at OpenQA.Selenium.Remote.RemoteWebDriver.StartSession(ICapabilities desiredCapabilities)        at OpenQA.Selenium.Remote.RemoteWebDriver..ctor(ICommandExecutor commandExecutor, ICapabilities desiredCapabilities)        at OpenQA.Selenium.Firefox.FirefoxDriver..ctor(FirefoxBinary binary, FirefoxProfile profile, ICapabilities capabilities, TimeSpan commandTimeout)        at OpenQA.Selenium.Firefox.FirefoxDriver..ctor(FirefoxBinary binary, FirefoxProfile profile, TimeSpan commandTimeout)        at OpenQA.Selenium.Firefox.FirefoxDriver..ctor(FirefoxBinary binary, FirefoxProfile profile)        at OpenQA.Selenium.Firefox.FirefoxDriver..ctor()        at SMT.Web.FunctionalTests.Drivers.Driver.GetWebDriver(Int32 browser, String page) 

I was expecting to be able to run the tests as per normal.

Has anyone experiencing the same thing? How did you resolve the issue?

Selenium version: 2.41.0 (Installed as a Nuget Package) OS: Windows 7 Browser: Firefox Browser version: 32

Answer 1

The latest Firefox version that Selenium 2.41.0 officially supports is 28. Downgrade your browser. According to the other answers, downgrading to Firefox 31 is enough to make it work.

It is always a good idea to have the latest selenium package installed. The strategy, though, is always the same - make sure that you are using the version supported by your selenium package browser.

Answer 2

That is correct. 2.42.0, and 2.42.2 will not work with FF 32. The failures is as follows: org.openqa.selenium.WebDriverException: Unable to bind to locking port 7054 within 45000 ms .

So the strategy is to roll back until 2.43 is released.
