Nope, no iframes, and no multiple body tags. I've done tests, and it's definitely firing twice on the same page. For now, my work-around is to set a variable on unsafeWindow, and if it's defined, I exit the script immediately. I still have no clue as to what is different in this page that causes it to trigger twice, and apparently not in FF3.6, but it does in FF12.
