Happening here; the issue is not that I can't work around it with a security exception, but that it should not require a security exception. The remote server is presenting a valid certificate signed by a CA certificate I have installed, there is no security exception to be made. I'm certainly not about to start adding invalid security exceptions!
Have downgraded to 15 to work-around for now. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1066585 Title: [Regression] Cacert CA certified certificate no longer recognized To manage notifications about this bug go to: https://bugs.launchpad.net/thunderbird/+bug/1066585/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
