Attached a javascript fragment extracted from the banking site www.egg.com (in a
ssl session behind a password) that when the html tries to change the status bar
text with javascript "window.status='something'" in a mouse over on the anchor,
the javascript throws an exemption "Permission denied to set Window.status" that
is caught and show in a pop up window.

IE shows the change in status bar text just fine. Not being a javascript coder,
I have no idea if this is a Mozilla problem, a website problem etc.

fragment to reproduce problem attached.

Reproducible: Always

You at some point disabled window.status access in your preferences (most likely
using UI in pre-1.0 builds that let you do this).

Quit Mozilla, delete the "capability.policy.default.Window.status" line from
your prefs.js, and restart Mozilla.  Things should be happy.
