title: Browser Mode / emulation setting for Firefox
body: <p>so on Internet Explorer if you load up the developer tools (F12) you have a nice drop down menu that lets you select the Browser Mode, IE 7, 8, 9 etc. Is there an option for this on Firefox? I've searched all over google etc and can't find anything like it. Really surprised if Microsoft have got one over on Firefox!</p>
  
  <p>I have firebug installed too but I didn't see anything in there about it either.</p>
