title: Focus tab or window
body: <p>for a little app, I'm opening a few windows/tabs from my script. Whether the browser opens a window or a tab is of course not in my hand.</p>
  
  <p>However, I hold the references to the newly created <code>window</code> objects and I do change their content "remotely" from another window. This all happens under the same <code>document.domain</code> so no xss problem.</p>
  
  <p>The problem is, I cannot reliably <code>focus</code> those created windows/tabs. Since I'm writing a very specific app for a customer, I'm only targeting Firefox as browser. One option I have is of course just to do a <code>remoteWindow.alert('foobar');</code> to get bring that window/tab up front, but that is pretty ugly isn't it.</p>
  
  <p>I found this answer <a href="https://stackoverflow.com/questions/3423470/how-to-focus-window-tab-like-alert">How to focus window/tab like alert()?</a></p>
  
  <p>and it's said there, that Firefox has an option to allow script focus. So finally my question is, what is that option ?
  I searched the <code>about:config</code> for "tabs" and "focus" but didn't find anything related.</p>
  
  <p>How to configure ?</p>
