Firefox and NSS incompatability

Hello All,

I'm having a problem I hope someone can help me with.

I'm running Linux 5 64 bit on a VM. I have Mozilla Firefox 38.3.0 installed and it is running great with 2048 bit certs. When I upgrade my NSS from nss-3.18.0-6.el5_11 to nss-3.19.1-1.el5_11, Firefox throws an error when going to an Oracle EM page.

Specifically, my browser reports,

Secure Connection Failed
An error occurred during a connection to . The server certificate included a public key that was too weak. (Error code: ssl_error_weak_server_cert_key)

I can find little on the web about this error, and what I do find points a finger at Mozilla. A lot of people are just downgrading Mozilla to solve the issue, but local customer requires the better security in v38.

Has anybody else run into this? Seen this issue before?
