Dear people,
problem: threaded view is enabled > when the child has a new message, the top message is not bold but only underlined. Without opening the thread, I wouldn't know that there are messages in the thread.
Example: Actual default style: In the view, it appears like this > Thread top message
v Thread top message
- Old Child message - New Child message
The style I prefer: In the view, it appears like this > Thread top message
v Thread top message
- Old Child message - New Child message
(see also screenshots for that).
As the solution in https://support.mozilla.org/en-US/questions/1265223 did not work anymore (since starting with Thunderbird 115+ the message list was rewritten from XUL treechildren to a HTML-based table view) I wanted to post another solution if someone stumbles upon this problem via google.
1) Enable customized stylesheet support: a) ☰ Menu → Settings → search for config → Config Editor b) Search for "toolkit.legacyUserProfileCustomizations.stylesheets" and enabled (set it to value "true") it by double clicking
2) Edit the Thunderbird styles by adding your customized stylesheet: 1) Help → Troubleshooting Information → Profile Folder → Open Folder 2) Inside that folder, create chrome/userChrome.css (folder name and filename must exactly named like this; pay attention to not create a userChrome.css.txt by accident when using an editor) 3) Put this into the userChrome.css: /* Collapsed thread that contains unread messages → bold */ tr[is="thread-row"].children[aria-expanded="false"][data-properties~="hasUnread"]
.subject-line span {
font-weight: 700 !important;
color: #000000 !important;
}
/* Keep correct color when selected */ tr[is="thread-row"].children[aria-expanded="false"][data-properties~="hasUnread"][aria-selected="true"]
.subject-line span {
color: var(--listbox-selected-text-color) !important;
} 4) Save the file and restart Thunderbird
