Hi Bryn, I have tested it in Thunderbird 52.8.0 in Ubuntu 18.04. It looks different, in that the "plus" signs are now arrowheads, but they do work and expand the sub list well. And the green button works to mark as "read" all the items in the sublist (even if the list is collapsed). I have attached a screen shot of a portion of my list.
I tried to create duplicate emails but it doesn't treat those as a thread (so, no arrowhead) but the green button works to make it "read." Am I trying this correctly? What version of Thunderbird do you have?

In the attached image there are several threads that clicking on the '+' sign has absolutely no action. I cannot click the green circle to mark the messages as read either. This doesn't happen ALL the time, but seems to happen in particular when duplicate messages are delivered (in this case a yahoo! groups mailing list that occasionally sends duplicates) ProblemType: Bug DistroRelease: Ubuntu 10.04 Package: thunderbird 3.0.4+nobinonly-0ubuntu4 ProcVersionSignature: Ubuntu 2.6.32-22.33-generic 2.6.32.11+drm33.2 Uname: Linux 2.6.32-22-generic x86_64 NonfreeKernelModules: fglrx Architecture: amd64 Date: Thu May 20 15:22:39 2010 ProcEnviron: PATH=(custom, user) LANG=en_CA.utf8 SHELL=/bin/bash SourcePackage: thunderbird To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/thunderbird/+bug/583577/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
