Firefox interchange not accepted by large corporations

I want to use Firefox. I like Firefox. But more and more, as I try to work with large corporations, Firefox won't work with their sites. Example: I tried logging into my FedEx account today and had problems. So I called FedEx customer support, and the fix was to use another browser. Firefox used to work with my FedEx login!? Many e-tail companies will not accept my credit info through Firefox - so I switch browsers - and no problem. Why is this?

A small dialog should appear. Click Start In Troubleshoot(Safe) Mode (not Refresh). Is the problem still there?
