And you do not even remember what the "function" was, right?  But "many 
others" said Firefox was the problem, therefore you just believed it.
Cargo cult programming.

Probably it was a this.focus() _method_ call (or equivalent), and probably 
those people were attempting to force the user to type something in that 
field because it was "required".  Such script-kiddie approaches to Web 
development are averted by the Firefox/Gecko UX people.  AISB.

That is why, AISB, you should handle the “keyup” event at a common ancestor 
element instead.

One of the first rules of thumb in programming is to avoid global variables.

Usenet is not what you want.  And I, for one, am not someone who will help 
you eating your soup with a knife, so that you will eventually cut your 
tongue in the process, because a knife is the only tool that you presently 
know; I am someone who introduces the spoon to you instead.  Which I did.
