i cracked restriction of 'zone' in mozilla.
("that's all" is the end of file if you are in a hurry)

[tested]
OS:"Windows Server 2003"

or
UMBRELLA.MX.TC ===> EdgeLink-MyPage section.
(disable Popup killer.)

[exp]
Mozilla does not wash links on the edge of transforming from one document 
to another.

{0}before content of the next document is loaded & after the security ID 
of current document is changed to the security ID of the next one(such 
period exists.):

{1}links including their "onclick" property in current document remain 
alive(=clickable).
{1.1}i can access my link if i have its reference.
now,i call its "onclick" via the reference of link:
{1.2}"onclick" is executed with security ID of the next page which is 
going to be loaded.
(boring? "[demo-exp]" is easier.)

[demo-exp]
okay, this is easier. listen up:

task:
show "document.cookie" at "www.securityfocus.com", via "window.alert".

[*]our "LINK" page: it's in our 'zone' and contains a link with 
onclick="alert(document.cookie)"

[*]"main" script lives in another page; 
now, "main" script plays the trick:
open "LINK" page in another window - "mywin".
save the reference of the link in "LINK" page to "MyLink" variable.
tell "mywin" to go to "http://www.securityfocus.com/".
wait until the security ID changes
("security ID changes"<==>"main script is unable to get protected info"--
>"try{[Get protected info in mywin]}catch{[now, security ID is 
changed.]}" )

call "MyLink.onclick()" *immediately*.
/*
we call that immediately, so the time is {0}(refer to "{0}" in "[exp]");
even though the security ID is changed to that 
of "http://www.securityfocus.com", our link remains alive.{1}
even though the security ID is victim's id, main script still can 
call "MyLink.onclick()".{1.1}
at last, {1.2}
*/

that's all.

[how]
