Just performed another previous step, removed Calendar-data and prefs.js files from new clean TB 91.2.0 and pasted in those files from working TB 78.13 and VOILA! Main calndar events and tasks appeared! So, why will these not show with the same files in the updated version of TB 91.2.0. Must have had something to do with previous addons now disabled and removed?
So, how do I move on forward from here in the most successful fashion? Updated TB 91.2.0 version has all of my email folders, etc., but no tasks and clean TB 91.2.0 has all of my tasks, but no email folders. What's the best way to get both in one, please? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1945368 Title: Thunderbird 91 forgets default calendar To manage notifications about this bug go to: https://bugs.launchpad.net/thunderbird/+bug/1945368/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
