That seems very likely.  The way that Japanese input works, the key
events are gobbled by the input method and Firefox will never see
them.  This is probably a good thing, since key events mean something
very different while the input method is active from what they mean
when they simply generate characters to enter in the text box one
character per keystroke.

I'm surprised that onChange() doesn't detect the addition of the text
to the box though.  That sounds like a Firefox bug.

No.  Since you're seeing weirdness in two places, I wonder if you
haven't inadvertantly been operating on an object that isn't the
button you want?
