How does this URL get around Popup blockers?

[QA]

Go to
http://dictionary.reference.com/search?r=67&q=apple
you see this
<!-- FASTCLICK.COM POP-UNDER CODE v2.0 for dictionary.com (12 hour) -->
<script language="javascript"><!--
var min_hour_frequency=12; var fastclick_site_id=4366;
document.write('<scr'+'ipt language="javascript" '+
'src="http://code.fastclick.net/pu.js"></scr'+'ipt>'); // -->
</script>
<!-- FASTCLICK.COM POP-UNDER CODE v2.0 for dictionary.com (12 hour) -->

Which will lead to
http://code.fastclick.net/pu.js
you see this
var date_ob=new Date();
document.cookie='h2=o; path=/;';
if(document.cookie.indexOf('e=llo') <= 0 && document.cookie.indexOf('2=o') >
0){
var bust=date_ob.getSeconds();
if(min_hour_frequency+0<12){min_hour_frequency=12};
date_ob.setTime(date_ob.getTime()+3600*1000);
document.cookie='he=llo; path=/; expires='+date_ob.toGMTString();
date_ob.setTime(date_ob.getTime()+min_hour_frequency*3600*1000);
var cap_ck='he=llo; path=/; expires='+date_ob.toGMTString();
document.write('<scr'+'ipt language="javascript"
src="http://media.fastclick.net/w/pop.cgi?sid='+fastclick_site_id+'&m=2&tp=2
&v=2.0&c='+bust+'"></scr'+'ipt>');
}

Which leads to
http://media.fastclick.net/w/pop.cgi?sid=4366&m=2&tp=2&v=2.0&c=
you see this
var ADSERVER_POPS_VAL=6;
var popupwin =
window.open('http://web.tickle.com/forward?sid=2239&supp=redswinglinegroupc1
uiq&test=uiqogt','PopWin',',menubar=no,resizable=yes,scrollbars=yes,toolbar=
yes,height=680,width=720');
popupwin.blur();

window.focus();

My question is how could the google toolbar does not block the pop?

I don't see that anywhere on the page you specified. There is some JavaScript
that refers to serverby.advertising.com, but it generates no popups or popup
attempts.

Because sleazy Web site authors are working 24 hours a day, 7 days a week to
defeat the popup blockers. And for every new design that gets around a popup
blocker, the popup blocker authors (hopefully) counter with a mechanism that
stops them.
