I'm not sure about the point that it doesn't come installed in firefox. This certificate whose Serial Number is "6e:cc:7a:a5:a7:03:20:09:b8:ce:bc:f4:e9:52:d4:91" does appears in my firefox certmanager on both window/linux.
Also, firefox does validate the SSL chain when connecting to a server not providing this intermediate certificate during the ssl handshake. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1226628 Title: ca-certificate seems to miss an intermediate certificate from verisign To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ca-certificates/+bug/1226628/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
