If you click on "popstate" you'll be taken to the definition of
"popstate"; if you click on it again you'll be presented with a list of
all the references. Or, you can just search for "popstate". Either way
you'll find that the only place that fires it is here:
The next question of course is "when is that algorithm invoked". If you
click on its definition (the bold text at the top of that section) then
you'll get a list of the places where it's mentioned. The exact answer is
rather subtle and I'm reluctant to try to summarise it.

How are you determining if Firefox fires the event? Are you sure you're
not just checking after Firefox has fired it?
