Hmm. I can reproduce the issue by putting the following line in /etc/thunderbird/syspref.js: pref("toolkit.telemetry.prompted", true);
However, if I set this in prefs.js in the user's profile, after a restart Thunderbird has changed this into user_pref("toolkit.telemetry.prompted", 2); Changing the syspref option to "2" instead of "true" seems to resolve the issue. Those that suffer from this bug, could you look into /etc/thunderbird/syspref.js if it has any prefs enabled? (The default file does not change anything). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1213744 Title: thunderbird stopped displaying folders To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/thunderbird/+bug/1213744/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
