Hi! I have the same problem. I have refreshed snap TB to stable/uri-debug. When I get dialog any change made to _Location_ field makes confirmation button inactive so it is impossible to test if full URI, with scheme will allow store confirmation.
BTW - mail server is using self signed cert, signed with local CA. I have added it in 'Authorities' tab of 'Certificate Manager' and still TB doesn't accept it. ** Attachment added: "Screenshot from 2025-11-04 01-40-42.png" https://bugs.launchpad.net/ubuntu/+source/thunderbird/+bug/1904789/+attachment/5923725/+files/Screenshot%20from%202025-11-04%2001-40-42.png -- 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
