Get Location of Window

[codefossa]

I'm havin' problems tryin' to get the location of a window I open.  I've tried ..

 

var tab = window.open('http://google.com', '_blank');
alert(tab.location);

 

Along with a few other ideas.  I know you can change it's location with

 

tab.location = 'http://example.com';

 

but it don't seem to let me grab the location.

 

Before someone points out how stupid it sounds to grab the location of a window you set the location to, the page I'm using uses a header redirect, and I need to use Javascript to get the new location.  It's a script added to each page with Greasemonkey to modify a site I use.

You can't do that because the other site is not on the same domain. Browser Security.

Is it possible to disable though?  -Firefox 6.0.2
