Thunderbird 60+ inconsistent tree icons

Hi everyone,

my tb tree view looks slightly strange.
Default folders have a old fashion icon theme, but custom imap folders have flat black icons.

Bug or normal state?
Is it possible to configure a consistent set of tree icons?


Using Cinnamon 3.8.9 with Papirus-Adapta icons.
(Switching desktop icon pack has no effect)
Thunderbird is plain vanilla without any tricky theming addons.

The black folder icon is controlled by your icon theme (Papirus-Adapta). If you change to a different icon theme like Vertex-Maia or any other non-Papirus variation, you'll see that the icon will be different (Thunderbird has to be restarted for this to take effect).

This icon is called folder.svg and can be found in /usr/share/icons/Papirus-Adapta/16x16/places/.

The other icons are used by default in Thunderbird regardless of the icon theme you're using. I don't know a way to change them, maybe installing a new theme for TB as an add-on from can do the trick (if that's what you want).

I hope this helps.

Thank you bill_t, this makes things clearer.

I think Mozilla should create some configuration options/dialog for the default theme.

Less is more. :+1: Finally i found a way to hide all folder icons.

CustomizeMyBird works with tb 60 and offers many visual configuration options.

Colored Folders is finally adapted for tb 60+.
Installing this addon provides also folder icon consistency :smiley:
