[RndTbl] weird cert problem

I get an error too with Firefox 30.0 and Firefox 33.1.1 on Windows 7, 
but not with Firefox ESR 31.2.0 on RHEL 5, nor with IE 11 on Win7.  With 
FF 30.0, it didn't even give me a chance to look at the cert or add an 
exception, but after updating to 33.1.1 I could. It's an Entrust, Inc. 
certificate, which doesn't seem like a no-name CA to me, particularly 
since many browsers accept it without complaint.  Maybe some Windows 
builds of Firefox are missing some root CAs or have a bug that prevent 
them from parsing all of the root CAs correctly?  Doesn't look like a 
MitM attack in any case.
