Firefox 7 does fullscreen browser window

I am unable to resize a browser window using javascript in Firefox 7. This code works in all the browser so far I 开发者_开发技巧have checked. Does anyone know why it is not working in firefox 7.

In my example I am trying to resize a window which is opened as a result of clicking a link in a parent window. Thus, I have 2 files here.

index.html (parent)

Head section

<script type="text/javascript">

function openwin() {
    var win1 = window.open('index2.html','mywin','left=20,top=20,width=900,height=700,toolbar=1,resizable=0');
}

</script>

Body section -

<a href="javascript:openwin()">Click to open a new window</a>

index2.html (child)

Head section

<script type="text/javascript">

function fullscreen() {
    window.moveTo(0,0)
    window.resizeTo(screen.availWidth, screen.availHeight);
}

</script>

Body section -

 <a href="javascript:fullscreen()">Click to fullscreen a window</a>

Please let me know if any help. I assume there is a bug with FF7. Many thanks

In FF6 you should use window.innerWidth or window.outerWidth and window.innerHeight or window.outerHeight to set window size, as shown here: http://www.java2s.com/Code/JavaScript/Window-Browser/SettingWindowHeightandWidthFirefox.htm
