This subject comes up every now and then - mutation event listeners work, but they're expensive.  If we could create a scriptable mutation observer, we could save some processing cycles.

A search on MXR shows this isn't badly needed:

Aside from tests, the only areas which use mutation listeners are the "places" bookmarkProperties.xul dialog, and the tab previews capability (which appears ifdef'd out right now per bug 465843, but I'm not totally sure of that).
