Nice Javascript Function on Firefox

Hi folks, today I’ve found a new (for me) firefox function : Find().
I’ve used this function in a “hand made” web site where a button “Find” would find a word inside a big list. My bad, I pressed two times the button and two windows appeared. That’s interesting…. So what happen if I call multiple find() functions directly from code ?

Firefox will load multiple find’s windows, of course, kind of cool !
So what happen if you try to load thousands of find windows ?
Does firefox die or all your PC will die ?

My Mac did ! :(
