Custom site frame killer code

Hi guys ,

I was looking for frame breaker code or frame killer scripts , In which i can Kill all frames expect Stumble frame , Plz help me .

I mean a frame killer code which kill all frames except Stumble frame

 

Something like this might work. Long time since i used the code, but should still work ( the exception not tested ).
Problem is that you cant get the outter frame url i think, so maybe checking the referrer works, if they dont hide it or fake it

<script type="text/javascript"> 
<!-- 
var ref = document.referrer;
// If outer most window location is not your loaded location
if (top.location != self.location) { 
    // If there is a ref and match stumble
    if (ref && /stumbleupon/.test(ref)) { 
        // Do nothing 
    } 
    else { top.location=self.location.href; } 
} 
//--> 
</script>

Code (markup):

 

Not working

 

Not working in overall? or just not for the stumble?
