How to run selenium with firefox driver

Question

I am trying to follow this link: http://www.seleniumhq.org/docs/03_webdriver.jsp

In SetUpTest:

protected IWebDriver driver;
protected ISelenium selenium;
[SetUp]
public void SetupTest()
{
    driver = new FirefoxDriver();
    selenium = new DefaultSelenium(
        "localhost", 
        4444,
        "*chrome",
        "http://localhost");
    selenium.Start();
    verificationErrors = new StringBuilder();
}

When this line driver = new FirefoxDriver();is executed, I have this error:

Additional information: Cannot find a file named '***[Link to my project]\webdriver.xpi' or an embedded resource with the id 'WebDriver.FirefoxExt.zip'.

When I change it to driver = new ChromeDriver();, it opens firefox, but it cannot find the element, although the element is already displayed.

If you used C #, it means that you added Nuget packages of both Selenium.NET bindings and Firefox Driver

Selenium , . Unit Test " NuGet". :
