问题
So I have created a Firefox extension and it works great, however when I submitted it (although it was accepted) it came up with one security warning. It said setTimeout() was removed in an else clause.
So, is there a way to listen for any DOM change? (or even a specific element changing, I have an ID for both). However, divs do not have an onChange event so any ideas?
I don't mind if it's ANY change, doesn't have to be div-specific.

DOMSubtreeModified event sound like something you want to use. Keep in mind, that it is deprecated and after some time its support will probably be removed from browsers.

It turns out adding an "onChange" event to a div works fine, although it might not be W3C valid it doesn't really matter as it's only a Firefox extension (plus it works!).
