title: Facebook login on headless browser
body: <p>My Facebook app has a function of automating tasks on server side headless browser (like visiting app links).
  Now, I use the Facebook SDKs to log user in and access user's news stream to search for links and other information. 
  Once the app has found all the links, it is supposed to pass this information in to the headless browser which will then proceed to visit in them for example. </p>
  
  <p>The problem is that these headless browser windows' are not logged in. I would like the headless browser to be temporary logged in as the user launching the tasks from the app.</p>
  
  <p>Is this possible?</p>
