c# - Firefox crash when I run selenium unit test

Question

I start use Selenium.WebDriver (v2.45) to run visual tests.

As web driver I use FirefoxDriver. I have installed Firefox 38. When I try run test firefox return exception with message:

FF has stopped working.

Does anyone have any suggestions? It worked in previous week, is it possible that my test was crashed by updated?

There is my test method body:

[Fact]
public void ShouldLoginForTestAccount()
{
    var driver = new FirefoxDriver();
    driver.Manage().Cookies.DeleteAllCookies();
    driver.Navigate().GoToUrl(LoginPage);

    driver.FindElementById("Login")
        .SendKeys("correctLogin");
    driver.FindElementById("Password")
        .SendKeys("correctPassword");

    driver.FindElementByTagName("button")
        .Click();

    Assert.Equal(TestingProjectUrl, driver.Url);

    driver.Close();
}

Answer 1

Selenium 2.45 does not reliably work with Firefox 38 due to compatibility issues.

Downgrade Firefox to 35 (link to 35.0.1).
