how can I reconfigure EMOC BUI to use other cipher as RC4

Since I disabled RC4 in my Firefox browser I can no longer connect to the Enterprise Controller BUI.

A check with 'sslscan' has proven that RC4 ciphers are the only ciphers supported by EMOC BUI.

$ sslscan oc:9443 | grep Accepted
    Accepted  SSLv3  128 bits  RC4-SHA
    Accepted  SSLv3  128 bits  RC4-MD5
    Accepted  TLSv1  128 bits  RC4-SHA
    Accepted  TLSv1  128 bits  RC4-MD5

My EMOC has release 12.2 .

As it is very unpractical to switch RC4 support on and off between EC and internet sessions I can no longer use my preferred web browser for Ops Center BUI.

Of course I want to use my preferred web browser for all web browsing.
