title: Stop Mozilla Firefox opening popups in a new tab
body: <p>I am building a site which when you click a link it opens up two things; it opens up a pop-up and an external website in a new tab. This is so the user can interact with the pop-up whilst he/she browses the external webpage.</p>
  
  <p>This was working fine for me but I think when my FF updated to version 15.0.1 on OSX lion, I can no longer get this to behave the way I want it to.</p>
  
  <p>I have even changed the settings in FF: FF->Preferences->Tabs->Open new window in Tab instead to off and with no such luck. </p>
  
  <p>I have also noticed that facebook connect on any site will open a new tab rather than a new pop-up too.</p>
  
  <p>I can't seem to find any documentation on the web stating that this is FF's native behavior, even in their changelog.</p>
  
  <p>Here is my javascript trigger which I am certain all the parameters are correct:</p>
  
  <pre><code>popWin = window.open('http://somesite.com','myTargetWindowName','height=650,width=450,pageXOffset=900,pageYOffset=900,scrollbars=yes'); 
  </code></pre>
