function isInspectOpen()
{
    console.profile(); 
    console.profileEnd(); 
    if (console.clear) console.clear();
    return console.profiles.length > 0;
}

from This Question

this function will return true is the user has the developer tools open

in response to your comment

$('#header').click(alert(isInspectOpen()))

is not properly formatted jQUery , try:

$('#header').click(function(){
   alert(isInspectOpen());
});
