I’ll add that Firefox and Internet Explorer both load about:blank asynchronously.
e.g. the first alert in
<script> var a = false; </script>
<iframe src=“about:blink" onload="a = true"></iframe>
<script> alert(a); /* or even setTimeout(function(){alert(a);},0); */ setTimeout(function(){alert(a);},10) </script>
will say “false” in both browsers whereas it says “true” on Safari and Chrome.
