I don't think you can really redirect to their default browser home page. But you can redirect them to the first page they went on when they opened up their browser (which is usually their homepage). This is the following code for a link to the first page the user went on:
<script type='text/javascript'>
function redirect()
{
window.history.go(-1 * window.history.length + 1);
}
</script>
<a href="javascript:redirect();">Go back to your home page</a>
