I middle clicked on the only open tab because that is the way i always got back to my home page (which by the way is the *Speed Dial* extension) and it just closed out firefox instead of taking me to my home page. Reproducible: Always Steps to Reproduce: 1.Go to any page and middle click Actual Results: The Browser Closed. Expected Results: Taken me to my home page like it does in version 3.0.4
