title: Connect to an already opened browser
body: <p>For a user already using Firefox (or any other) is there a way to connect to that browser using selenium?</p>
  
  <p>Conditions: </p>
  
  <ul>
  <li>the browser icon was <strong>clicked on</strong> by the user.</li>
  <li>i do not want a new window to pop up (when using selenium).</li>
  </ul>
  
  <p>Example: a user wishes to log into Facebook and wants a program to enter his lengthy password (i can do this with the webdriver etc...). </p>
  
  <p>Is there a way to connect (to an already opened browser) and send commands to that browser?</p>
