How do I launch the browser using Selenium WebDriver?

• Create a new WebDriver instance for a specific browser.
• Call Navigate() to retrieve a navigation object.
• Then call GoToUrl(...) method and pass the URL that you want the browser to navigate to as a parameter.

 Long story short, do something like this:

using (var driver = new FirefoxDriver())
{
  var url = "https://www.bettercoder.com";
  driver.Navigate().GoToUrl(url);
}

If you are wondering what the "using" keyword is good for, it's a C# way to release the driver from memory once it's not needed anymore.
