In trying to set up an online account, a diagnostic informed me that I should update my browser to accept 128 bit security encryption. How do I accomplish this? I already have Firefox 4.

I can't understand why my browser would not be compatible with 128 bit security encryption. Have set up several other accts with no issues. What are possible problems related to this non-compatibility?

Firefox 4 supports AES-256 (256 bit) encryption in addition to 128 bit since Firefox 2 in 2002.
