I have checked
  • Ubuntu 14.04
  • Firefox 35.0.1. Mozilla Firefox for Ubuntu canonical - 1.0
  • Web Call Server 4 - 1333, Web Client - 670.1331
It works for me.

It looks like a networking issue. FF can't use network interfaces on your PC by some reason. Please install latest versions of WCS and check it.
