Confirm User Exit

Here is some code that alerts users that leaving the page might be a bad idea. It counts the number of attempts to leave the page and stops displaying the message after n attempts.
function confirmExit(){
if(!this.times) {this.times=0}
times++; if(times==2){window.onbeforeunload=''}
return 'All your sensitive information (email,posts,Google searches) '+
'is gathered by smart routers and warehoused in your namespace';
window.onbeforeunload= confirmExit;
