close browser code updated into Flash 9

Hi there,

I'm trying to get some old close browser code updated into Flash 9 and am having troubles.

I have this in my index.html file

<script language="JavaScript">
window.open('test.html','1','fullscreen=yes,scrollbar=no');
</script>

and then this code on a button in my flash file to close test.html

on (release) {
getURL("javascript:self.opener=self;self.close();");

}

i've also tried:

"javascript:window.open('','_parent','');window.close();");

and

"javascript:window.close();"

and

"javascript:window.opener=self; window.close()"

and

"JavaScript:self.close();"

but none of these seem to work in Firefox. Can anyone help?

Thanks in advance.
