Using FF 45.x ESR on RHEL6 to access a directly connected VNX 5300. Java was updated recently on the RHEL server, and I have not been able to get the Unisphere login prompt to fully load ever since. The app appears to load fine....until the splash screen is supposed to show the username & p/w boxes. The Unisphere Logo and version appear as normal, but the login boxes aren't there. I've lowered Java security in every way I've been able to find, told Firefox to accept everything, cleared all temp files from Firefox and Java, and tried reissuing the self-signed cert from the VNX itself, but nothing has changed.

Querying for the installed Java version returns:

Java SE Runtime Environment (build 1.7.0_111-b13)

Java HotSpot 64-bit Server VM (build 24.111-b13, mixed mode)

Firefox reports the installed Java Plug-in version 10.111.2.

What should I try next?
