Hi all,
while surfing techtree.com i have come to this piece of information, that says none of browsers is safe as per this test and condition explained there in which is:

"Secunia Research has discovered a vulnerability in various browsers, which can be exploited by malicious web sites to spoof dialog boxes.

The problem is that JavaScript dialog boxes do not display or include their origin, which allows a new window to open e.g. a prompt dialog box, which appears to be from a trusted site.

Please use the test below, to see an example of how this vulnerability can be exploited, and also to determine whether or not your browser is vulnerable."

Test is given here:


I can't understand this much so if anyone can also explain me in laymen terms please help me
