   I've seen no studies that would answer this question.  I think the short
answer is that tabs are new to many users and there's no evidence that theyy
fully understand the scoping rules.

   I'm currently looking at the tabs in FireFox 2 (see the attached page).
One interesting feature of the way tabs are presented by FireFox 2 is that
they are drawn to encompass everything _below_ them.  In Firefox, this
includes page content but not the address bar or security information.

   The FireFox 2 tabs contain a window close button that used to be part of
the window frame.  Presumably they were moved here because users didn't
understand, or weren't comfortable with, the model in which a close icon for
the window closed a tab.  Firefox 2 tabs also contain the notorious site
FavIcon (e.g. the tab for Markus Jakobsson's page contains a lock icon.)  It
appears the site-specified FavIcon won out for space over the
browser-specified lock icon.
