Set a global variable a=1; then in function check for variable's value. After windows.open is executed, change the global variable's value, so that windows.open will not be executed again.

Code:

<script>
var a=0;
function popup() {
if(a==0){
window.open ("http://www.stackoverflow.com","popup","menubar=1,resizable=1,width=450,height=550");
a++;
}
}
</script>

Firstly you will need to define to yourself what a visit consists of, i.e. once per day, week, or each time a users lands on your site, every page loaded, etc.

Assuming you want some persistence for your users while they browse, what you need to do on your site is set a condition to be evaluated prior to the first click and if the result indicates a users' first visit then open the page. At the same time, set a value to be checked next time (and most likely all subsequent clicks based on your current implementation). LocalStorage or cookies would be your best options for this.

I would set up something along the lines of:

//check page is loaded
if (cookie.firstVisit) {
  //add click event listener
} else {
  //set cookie.firstVisit to false
  //remove click event listener
}

Instead of spelling out how to do this with cookies here, have a look at this article which explains it all: How to set/unset cookie with jQuery?

Lastly, opening a new window when someone clicks anywhere on your page without them explicitly wanting that action perform is considered bad practice in most scenarios. However, I do not know your situation so this may be the best course of action but thought it was worth mentioning.
