I updated Thunderbird to version 60.3.1 my folders lack the icon to expand or collapse. If I click on the place where the small + or - used to be, just before the icon of the folder, the folders expands (or collapse) I use Debian with gnome.

Thanks for your answer. The problem is not solved, it looks the same as in normal mode. My theme is the default theme. If I select another theme, the problem stays the same.

I had the same problem, but I don't remember the Gnome version I was using at that time. I'm now on Gnome 3.26 and there is no problem.

I'm afraid I had to update Debian.
