It is changed not to be able to access chrome.extension on a window.unload event in a popup.

Now, I've resolved this error.

// error
window.unload = function() {
    var ex = chrome.extension; //error : Expected an object as the target scope
}

// fixed
function access_extention() {
    var ex = chrome.extension; 
}

window.onblur = access_extention;
window.onbeforeunload = access_extention;
