I have a Citibank credit card that I use for certain types of purchases.  For a long time I've had a problem with the web site they provide customers for checking their bills and making payments.  For some reason the site won't let me download statements if I use Firefox on my Mac.  I've had to use Safari instead.  Well, today I logged in and tried to use the site, but today the whole menu is inactive.  I get a javascript error when I tried to select something from the menu.  Okay.  So, I sent an email to their customer service department to tell them about the problems with Firefox on the Mac.  This was their response:

Thank you for your inquiry.

Unfortunately, we do not test or support our website for MAC.

It's not April 1 any more, so I guess this isn't a joke.  It should be.  How can a major corporation's customer service web site not support the Mac? 

Astounding.
