/* Force BG in unthemed folder */
 --foldertree-background: #A99B92 !important;
 /* Force BG in threads */
 --tree-view-bg: #A99B92 !important;
 /* Force black text in threads */
 --tree-view-color: #000 !important;

I've been using color settings in userChrome.css to set the colors for the threads and folder panes... I obtained these settings from a discussion in the Thunderbird Beta mailing list, back in 2023. Here are my current settings: :root { /* Force BG in unthemed folder */ --foldertree-background: #A99B92 !important; /* Force BG in threads */ --tree-view-bg: #A99B92 !important; /* Force black text in threads */ --tree-view-color: #000 !important; } /* Position Menu Bar above Unified Toolbar */ #toolbar-menubar { order: -1 !important;} However, after the most recent beta update, the tree-view settings are no longer working, and I'm stuck once again with the ghastly Bright White background... see the attached image; note that the foldertree setting is still working though... What do I need to do, to get this code working again? or is this a bug in the current beta?
