Also using the snap on KDE and having a symlink downloads folder on another drive, I also could not send or save any messages, and the workaround (sudo snap connect thunderbird:removable-media) worked for me too.
Checking the Thunderbird error console previously showed "NS_ERROR_FAILURE: Component returned failure code: 0x80004005" when attempting to send or save a message, which is resolved with the workaround. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2065542 Title: Thunderbird snap unable to send or save messages with custom download dir location To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/thunderbird/+bug/2065542/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
