New thunderbird user here. When in cards view, and threads enabled. If a thread is collapsed and a new message arrives, it only underlines the thread subject and sender. This makes it easy to miss. I'd like it bold, or change the background or something to scream out "HEY! you got a new message in here dummy" heh.

I followed these posts but it doesn't change it for me. https://support.mozilla.org/en-US/questions/1265223 https://support.mozilla.org/en-US/questions/1366417#answer-1479972

I tried adding @namespace url("http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul"); didnt work. I made other changes that I found in other threads so i know my userChrome.css does indeed "work" or is recognized by Thunderbird.

Help pls :) Thanks in advance!!!!

The css in those topics doesn't work in TB 115. Based on the methods posted here, I found some code that works for Table View and Cards View. It bolds the top message in a thread with unread messages.

/* bold top msg in thread with unread */

tr[is="thread-row"].children.collapsed[data-properties~="hasUnread"]
  :where(td, .subject-line) {
  text-decoration: none !important;
  font-weight: bold !important;
  color:  var(--thread-pane-unread-color) !important;
}

tr[is="thread-card"].children.collapsed[data-properties~="hasUnread"] :is(.sender,.date,.subject) {
      color: black !important;
      font-weight: bold !important;
}


Help/Troubleshooting Info, Profile Folder, Open Folder, close TB, create a new folder named chrome, create a new document in chrome with a text editor, name it userChrome.css, Save as type: All files *.*, copy in the above code, change the colours as desired. Double-click toolkit.legacyUserProfileCustomizations.stylesheets to true in Settings/General/Config. editor, restart TB.
