Hi Am facing some trouble with firefox - on some sites that require secure connections - like ticket bookings, passport sites etc. The problem is when i click on some links i get this message (below between the ***) **** This Connection is Untrusted You have asked Firefox to connect securely to <a href="http://passport.gov.in">passport.gov.in</a>, but we can't confirm that your connection is secure. Normally, when you try to connect securely, sites will present trusted identification to prove that you are going to the right place. However, this site's identity can't be verified. If you usually connect to this site without problems, this error could mean that someone is trying to impersonate the site, and you shouldn't continue. *Technical Details* <a href="http://passport.gov.in">passport.gov.in</a> uses an invalid security certificate. The certificate is not trusted because the issuer certificate has expired. (Error code: sec_error_expired_issuer_certificate) *** am using firefox 3.5 in Ubuntu. I downloaded the firefox tar.gz and extracted it and copied the extracted folder to /home/user/.mozilla/ and made links to the firefox shell script there. am wondering if this error has anything to do with Firefox 3.5 and the fact that its not updated on 9.04 via the normal update routes ram
