Try this

function preventBack() { window.history.forward(); }
setTimeout("preventBack()", 0);
window.onunload = function () { null };

You cannot disable the Browser button, however you can prevent it to use.

Following code may help you -

JavaScript

<script type="text/javascript" >
   function preventBack(){window.history.forward();}
    setTimeout("preventBack()", 0);
    window.onunload=function(){null};
</script>
