title: Selenium on Anaconda 2 not opening firefox
body: <p>I'm a beginner python user and try to use selenium to open Firefox on Win 10 and Anaconda 2.5. I just downloaded Firefox and installed selenium on Anaconda, so they are up to date.
  When I type the following:</p>
  
  <pre><code>from selenium import webdriver
  browser = webdriver.Firefox()
  </code></pre>
  
  <p>Firefox open in the task bar for a second and disappears. But if I close the cmd line, Firefox opens on the window. The cursor on the cmd prompt is flickering so when I wait, then I get the error message. How can I solve this?</p>
