Unfortunately I can confirm the bug on a self-hosted dovecot server with snakeoil certificates.
When I start Thunderbird (140.4.0esr Ubuntu 24.04.3 LTS) in a terminal I get this message when clicking on "Confirm security exception": JavaScript error: chrome://pippki/content/exceptionDialog.js, line 162: NS_ERROR_MALFORMED_URI: Component returned failure code: 0x804b000a (NS_ERROR_MALFORMED_URI) [nsIURIMutator.setPort] -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1904789 Title: [snap] Cannot confirm security exception for invalid certificate To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/thunderbird/+bug/1904789/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
