That seems pretty bad.

For firefox, had to follow this: http://stokebrand.com/blog/2015/7/6/cannot-login-to-cisco-callmanager-after-firefox-update
For Java, I had to drop the security from very high to just high, disable some "Block these apps" settings and add an exemption for the https://IP:port of the CUCM server.

For those who don't want to follow the link for firefox, I had to set these in about:config
security.ssl3.dhe_rsa_aes_128_sha=false
security.ssl3.dhe_rsa_aes_256_sha=false

Perhaps you need to setup a VM specifically for managing that old equipment.
