For several weeks now I have been a Bad Request error when trying to sign into my bank account:

Bad Request

Your browser sent a request that this server could not understand. Size of a request header field exceeds server limit.

Things work fine when I use Google Chrome, but I do not view that as a long-term fix. Can you help?
