In short, SPE has never claimed to fill passwords. That's still left as the job of Firefox, as to do otherwise would turn SPE into a password manager, not a password *editor*. If Firefox doesn't do that properly, you'll need other solutions, one of which I suggest at aforementioned support site.

If you want to complain about this, please complain to Mozilla developers.
