If you enable popups and go to (this site attempts
to trick people into giving out their credit card details), a popup is opened
with an illegitimate page contained within, and behind it, a legitimate web page
is opened. The user could be tricked into thinking that this popup is part of
the legitimate page behind.
Even Internet Explorer has got round this problem, because in the title bar of
the popup, it displays the real address ( FireFox
does not.

Reproducible: Always

Steps to Reproduce:
1. Enable popups.
2. Go to

Actual Results:  
A popup that appears to belong to the legitimate page behind it is opened.

Expected Results:  
There should be some kind of indication that this popup is from a different website.

Note that is a website attempting to defraud people,
which is sent out in spam messages.
In 1.0.x builds the popup titlebar also contains the site in Firefox. In 1.1 we
will either do that or put the sitename in the statusbar as we do for secure pages.
