And with that comes the next release of our new 
  MSDN Online Library (we are still in 
  beta as well). I'm really excited about this, not only have we "in process" of 
  migrating the Library content to XML, but we was able to craft up a 
  "sweet" cross browser user interface. Check it out in FireFox! It will 
  appear almost identical to what you in IE. Yes, there is a "deep tree"! Yes, 
  you can resize the "psuedo-frameset", and yes, it persists these setting 
  between visits (ok, you'll need to have javascript and cookies enabled!). 
  There is no longer the need for the "sync TOC"! Need to collapse the "frame" 
  use ? Use Shift-T.
Bene bene... sono proprio contento...
