Bad Firefox implementation of SSL/TLS (error: ssl_error_no_cypher_overlap, RC4 and 3DES are turned OFF)

When I turned OFF RC4 and 3DES Firefox can't connect to some SSL-server. But Internet Explorer and Opera with the same (absence of RC4 and 3DES and to the same server) can do it.

Why? I think this is the BAD implementation of SSL/TLS or a BUG!

And why in Firefox there are no cipher suits with SHA-256? I see in ServerHello a cipher suite(choosen by server): TLS_RSA_WITH_AES_256_CBC_SHA256 (0x003d) But this cipher suite absent in Firefox!

I think that it is best to keep the discussion in one thread, so I locking the other two that you created.
