title: Browsing with a Session per Tab
body: <p>I need to login to a site that I am developing with four different users at the same time.</p>
  
  <p>Currently, I am using four different browsers, or two browsers (chrome and firefox) two times (incognito-private / normal)</p>
  
  <p>But this arrangement is tedious. I do not want to have four windows. <strong>I want only one window with four tabs.</strong> Using tabs is easier and faster for me because I will be switching between tabs constantly.</p>
  
  <p>Yoono plugin for firefox seems to do what I want but I prefer to stay away from a service that makes me register one social network.</p>
  
  <p>I am not constraint to any of the major browsers. I could use Firefox, Chrome, or IE (for windows).</p>
  
  <p>Is there a Windows browser that have session per tab? Or a plugin for one of them to accomplish the same task?</p>
