In the page at http://jaysolomon.net/ssc/contact/index.html you will see that
when you first get to the page it will set focus on the first form field using
setTimeout("document.forms[0].fieldname.focus()",10), but if you click reload in
the browser i get the following javascript error:

Error: [Exception... "'Permission denied to get property
XULElement.selectedIndex' when calling method:
[nsIAutoCompletePopup::selectedIndex]"  nsresult: "0x8057001e
(NS_ERROR_XPC_JS_THREW_STRING)"  location: "JS frame ::
http://www.jaysolomon.net/ssc/scripts/contact.js :: <TOP_LEVEL> :: line 3" 
data: no]
Source File: http://www.jaysolomon.net/ssc/scripts/contact.js
Line: 3

I only get this error when i click reload. This happens on every "reload"

Reproducible: Always
Steps to Reproduce:
1. Open The URI
2. Let it finish loading
3. Click Reload / Refresh in the browser toolbar

Actual Results:  
The form field does not get focus and you get the following JS error:
Error: [Exception... "'Permission denied to get property
XULElement.selectedIndex' when calling method:
[nsIAutoCompletePopup::selectedIndex]"  nsresult: "0x8057001e
(NS_ERROR_XPC_JS_THREW_STRING)"  location: "JS frame ::

data: no]

Line: 3

Expected Results:  
Set focus on the first field
