Listen for localStorage.setItem on same Window (FireFox & IE)

Question

I found this thread that answers partially:

Listen for changes with localStorage on the same window

Although it works in Chrome, I still wasn't able to figure out how to work on Firefox or IE.

Answer 1

Storage interface emits storage event on global objects which it affects.

window.addEventListener("storage", function () {
    // your code
}, false);

this event will also be triggered when you use setItem .
