Re: New possible scam method : forged websites using XUL (Firefox)

Along the same lines I took a look at the spoof using my customized firefox and it was an obvious fake -

1.  The font is wrong
2.  The window size is wrong (it is twice the width of my browser window and
    almost 50% longer)
3.  The fake toolbar was below my toolbar so both were viable
4.  The address bar was also in the wrong place so I had two.
5.  I also had two status bars

Isn't a possible solution to disable any overlaying of existing elements (toolbar, status bar, address bar, etc.) once they are loaded from the browser's and user's on disk config? Lock them even before opening a socket to connect to a site.

Of course if there is an exploit to modify the on disk files then this won't work.

More on the lines of "few people know that Mozilla can do that":

So I started to look for the "existing pref", and sure enough, if you

user_pref("dom.disable_window_open_feature.location", true);

in your prefs.js, the spoof looks much less convincing.
(You can also set this preference via "about:config".)
