Ummmmm -- what part of "address bar spoofing" did you not understand?
_IF_ the URL spoofing part of a URL spoofing vulnerability in one
browser does not work in another browser, then that other browser is
clearly NOT vulnerable to the first browser's URL spoofing
vulnerability.
The issue Robert reported is NOT that Opera and Konqueror parse the
data: protocol, BUT that cunning use of a data: protocol URL can be
used to fool the user to think they're somewhere other than they are.
As you so clearly -- and accurately -- say yourself, the URL spoofing
part of this does not work in FF, so we should give a rat's arse that
FF handles data: protocol URLs why?

Nick FitzGerald
