Firefox cannot open portal.unisys.com unless I set my PC's date prior to 07/01/2011. It states a expired certificate, but the certificate expires in 2012. IE works, but sucks. This started on 07/01/2011.

Beginning 07/01/2011 Firefox began displaying a message that certain sites are untrusted. It states an expired certificate, yet the certificate expires in 2012. I am unable to add an exception as Firefox doesn't allow selection of the "Confirm Security Exception" button. The site works fine in IE, but I refuse to use it if possible. if I roll back the date on my PC to 03/30/2011 it works fine.

Edit: I've also noticed that if I try to manually add an exception Firefox states that "This website provides valid, verified identification. There is no need to add an exception."

I can see a difference between Firefox and IE: IE has a chain of certificates up to a trusted root, and Firefox does not. Usually, it is the web site's fault if it does not send all of the intermediate certificates.

The date thing is a head-scratcher. I don't understand why that would make a difference, unless it allows access to a cached version of the old intermediate certificate.
