Hey, dude I also have got a shortcut which will directly pop out the Facebook Chat in your Google Chrome tab. And it won’t even require installing any kind of extensions or software. It is just a small trick. Add the below bookmarklet to your bookmarks bar. It would be better if your name it for remembrance like you can call it Fb chat.
Code:
javascript:var popup=window.open('http://www.facebook.com/presence/popout.php', 'http://www.facebook.com/presence/popout.php','width=750, height=500, location=no, menubar=no,status=no, toolbar=no, scrollbars=yes, resizable=yes');
