You seem pretty certain it is firefox's issue. Did you try another
browser or completely deleting your user profile from Firefox?
How about outputting cache control headres like the following that I
ripped off the PHP site?
header("Cache-Control: no-cache, must-revalidate"); // HTTP/1.1
header("Expires: Sat, 26 Jul 1997 05:00:00 GMT"); // Date in the past
