My opinion is that ; you shouldn't do it because of causing bad user engagement. It also makes your page untrustable.

But for chrome and firefox this should be work;

Put This script on head of your page and change 'pagename' to your page name.

<script type = "text/javascript" >
    history.pushState(null, null, 'pagename');
    window.addEventListener('popstate', function(event) {
    history.pushState(null, null, 'pagename');
});
</script>

Note: This script must be on head of your page.
