Cross browser testing in Firefox Ver 45 with selenium component.


  • Hi,

    Does selenium component for Coded UI Cross Browser Testing work for Mozilla Firefox ver 45?

    The official site for selenium component for Coded UI Cross Browser Testing says it supports Firefox ver 33. What does it mean? How to script in this case if it supports. any change compared to chrome? 

    I had been automation testing with the Selenium components for Coded UI Cross Browser Testing in Chrome. I wanted to do the same in Mozilla Firefox 45. I tried the same process as I do in Chrome – Changed the current browser to Firefox and handle the code for browser specific events wherever required. But it doesn’t work. The browser opens, but it fails to load the ip and also fails to run the  rest of my script.

    Here is the code snippet I use for launching the browser

    public void OpenBrowserWindow(string currentBrowser, string browserProperties, string browserPropertyValue, string ip)


                BrowserWindow.CurrentBrowser = currentBrowser;


                BrowserWindow browser = new BrowserWindow();

                browser.SearchProperties.Add(browserProperties, browserPropertyValue, PropertyExpressionOperator.Contains);

                browser.Maximized = true;


    Exception that happens at BrowserWindow.Launch(ip) –

    An exception of type 'OpenQA.Selenium.WebDriverException' occurred in WebDriver.dll but was not handled in user code

    Additional information: Failed to start up socket within 45000 ms. Attempted to connect to the following addresses: ***.*.*:****

  • Hi SandeepPRaju,

    According to your description and code snippet, I create a sample Coded UI Test project which just contains one method that used to open site with Firefox browser. The version of Firefox browser is 45.0 and I get the same error message with yours.

    Then I uninstall my Firefox 45.0 and install the version 33.0, it can open the assigned site with Firefox 33.0.

    So I'm afraid that the Selenium Component for Coded UI Cross Browser Testing is just support Firefox 33.0 now. And in the Q&A of the Selenium Component for Coded UI Cross Browser Testing download site, there are other communities also has this issue.

    I suggest you contact the author to submit this issue.
