Hi Felix, thanks for your explanation. I checked and official Mozilla's Thunderbird build uses GTK3. The file ~/.config/gtk-3.0/gtk.css didn't exist in my home directory and I copied /usr/share/themes/Breeze/gtk-3.0/gtk.css to ~/.config/gtk-3.0/ and changed line #3133 from min-width: 14px; to min-width: 7px; This line is under scrollbar button selector and scrollbars are now tiny :) Thank you very much.
