I upgraded and it didn't help. I viewed the certificate in FF and all the info is there except FF has this line twice that I don't see using the other browsers "Organization (O) Not Part-Of Certificate"

>>I have an interesting problem. I just installed a renewed cert from register.com. Now FF (3.6.10) says it can't determine the issuer but chrome and IE work just fine. I called register support and they were able to user FF (3.6.8) just fine. Anyone seen this problem before?
