title: Selenium install Marionette webdriver
body: <p>I have this issue with firefox version 47 <a href="https://github.com/seleniumhq/selenium/issues/2110" rel="noreferrer">https://github.com/seleniumhq/selenium/issues/2110</a></p>
  
  <p>So, i have tried to add Marionette web driver to fix it: <a href="https://developer.mozilla.org/en-US/docs/Mozilla/QA/Marionette/WebDriver" rel="noreferrer">https://developer.mozilla.org/en-US/docs/Mozilla/QA/Marionette/WebDriver</a></p>
  
  <p>But:</p>
  
  <pre><code>from selenium.webdriver.common.desired_capabilities import DesiredCapabilities
  
  firefox_capabilities = DesiredCapabilities.FIREFOX
  firefox_capabilities['marionette'] = True
  firefox_capabilities['binary'] = '/Users/myproject/geckodriver-0.8.0-OSX'
  </code></pre>
  
  <p>returns error:</p>
  
  <blockquote>
    <p>selenium.common.exceptions.WebDriverException: Message: 'wires'
    executable needs to be in PATH. </p>
    
    <p>Exception AttributeError: "'Service' object has no attribute
