I believe this behaviour is as-designed, since our interpretation of wildcards is specified to only go one level "deep." In any event though, moving this to NSS, where the decision is made.

Historically, Mozilla has been the only browser that allowed a wildcard 
character to match multiple levels of subdomain.  This behavior did not 
conform to the relevant RFC, and became viewed as a security risk, so 
Firefox 3.5 has changed to conform to RFC 2818.  See bug 159483.

Insane that one needs to tell people to do the following:

You will need to click on the "Add Exception..." link, ignore the warning about "You are about to override how Firefox identifies this site. Legitimate banks, stores, and other public sites will not ask you to do this.". Click on "Get Certificate" and then click on "Confirm Security Exception".
Comment 4 Nelson Bolyard (seldom reads bugmail) 2009-07-04 12:40:24 PDT
Almost as insane as people putting certificates on their web servers that
do not match the DNS names used by those servers, and then expecting all
to work without any errors.
