title: Go-selenium: No connection could be made because the target machine actively refused it
body: <p>I tried going to windows firewall and opening port 4444, however this still does not work. This is the complete error I'm getting: </p>
  
  <pre><code>Failed to open session: Post http://localhost:4444/wd/hub/session: dial tcp [::1]:4444: connectex: No connection could be made because the target machine actively refused it.
  </code></pre>
  
  <p>And lastly this is the package I'm using: "sourcegraph.com/sourcegraph/go-selenium". I never ran into this problem in python but I assume the whole application was allowed through the firewall, so if I could do that for go that would be great.</p>
  
  <p>Edit: All my code (stolen from the github example)</p>
  
  <pre><code>package main
  
  import (
      "sourcegraph.com/sourcegraph/go-selenium"
      "fmt"
  )
  
  func ExampleFindElement() {
      var webDriver selenium.WebDriver
      var err error
      caps := selenium.Capabilities(map[string]interface{}{"browserName": "firefox"})
      if webDriver, err = selenium.NewRemote(caps, "http://localhost:4444/wd/hub"); err != nil {
          fmt.Printf("Failed to open session: %s\n", err)
          return
      }
      defer webDriver.Quit()
  
  err = webDriver.Get("https://sourcegraph.com/sourcegraph/go-selenium")
  if err != nil {
      fmt.Printf("Failed to load page: %s\n", err)
      return
  }
  
  if title, err := webDriver.Title(); err == nil {
      fmt.Printf("Page title: %s\n", title)
  } else {
      fmt.Printf("Failed to get page title: %s", err)
      return
  }
  
  var elem selenium.WebElement
  elem, err = webDriver.FindElement(selenium.ByCSSSelector, ".repo .name")
  if err != nil {
      fmt.Printf("Failed to find element: %s\n", err)
      return
  }
  
  if text, err := elem.Text(); err == nil {
      fmt.Printf("Repository: %s\n", text)
  } else {
      fmt.Printf("Failed to get text of element: %s\n", err)
      return
