My bank's (Suntrust) bill pay website can be fooled into accepting Firefox (which works just fine) by using "User Agent Switcher". http://chrispederick.com/work/useragentswitcher
This little program simply hides the fact you are using Firefox by telling the offending website that you're using IE (or Netscape or Opera). It doesn't work everywhere, many sites actually require IE

Have you complained? It's the only way to get things to change. It's obvious that if simply setting the user agent makes everything work, that there is no valid reason for them to attempt to make you use an insecure and buggy kludge like IE on a banking site.
