Public bug reported: When Thunderbird is first started, the folder pane is blank. (See attached screenshot.)
When it is started the second and subsequent times, the folder pane is displayed properly. This was happening for me with 16.04 too. $ lsb_release -rd Description: Ubuntu 16.10 Release: 16.10 $ apt-cache policy thunderbird thunderbird: Installed: 1:45.3.0+build1-0ubuntu4 Candidate: 1:45.3.0+build1-0ubuntu4 Version table: *** 1:45.3.0+build1-0ubuntu4 500 500 http://gb.archive.ubuntu.com/ubuntu yakkety/main amd64 Packages 100 /var/lib/dpkg/status ** Affects: thunderbird (Ubuntu) Importance: Undecided Status: New ** Attachment added: "thunderbird not showing folder panel.jpg" https://bugs.launchpad.net/bugs/1635208/+attachment/4764262/+files/thunderbird%20not%20showing%20folder%20panel.jpg -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to thunderbird in Ubuntu. https://bugs.launchpad.net/bugs/1635208 Title: On first start, folder pane is left blank Status in thunderbird package in Ubuntu: New Bug description: When Thunderbird is first started, the folder pane is blank.
