Do you mean controlling the popup blocker settings of the browser? If so, that's not possible with JavaScript.

If you want to detect if a popup has been blocked, that should be possible.

When you create the popup using window.open, assign it to a variable and then check if that variable is defined, e.g.:
[code=javascript]var popup = window.open(... );
if (!popup) ...[/code]
