hello, i can certainly replicate this issue. my guess is that the site is currently implementing measures against the recently published widespread vulnerability that allows webservers with a certain version of openssl running on them to be exploited (heartbleed.com) & is switching their certificate.

an advanced security feature in firefox is picking up this change as the site doesn't seem to be fully updated for this new certificate yet. you can temporarily work around the issue:

enter about:config into the firefox address bar (confirm the info message in case it shows up) & search for the preference named security.ssl.enable_ocsp_stapling. double-click it and change its value to false.

it is important however, that after a bit of time when the issue gets resolved by the site (maybe try again in 24 hours), you go back and switch the setting to "true" again!
