Color differentiation of messages in list seems erratic

I'm on a Mac using the "dark"theme. When viewing any list of messages, the one that is selected is not highlighted the same way. Sometimes, it seems as if even-numbered messages appear with a golden color when selected, and other times, they appear without the golden color, but still show as selected with a pale gray color. Other times, I can select a message but there is no indication at all that it is actually selected.

Also, when switching the sort order of any column by clicking the column title, there is no longer the up or down arrow to indicate the sort order even though the sort is working as expected.

Also --- some very old messages that have the status "Replied" appear in red text, but newer ones do not.

I guess I am looking for the place in preferences where these settings can be adjusted.

The color of selected messages in the dark theme is barely distinguishable from the background, but fortunately this can be corrected with css.

1. Help/Troubleshooting Information, click Show in Finder, close TB. 2. Create a new folder named chrome. 3. Create a new file in chrome with a text editor, save it as userChrome.css. 4. Copy this into the css file: 

@namespace url("http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul");

#threadTree treechildren::-moz-tree-row(selected) {
  -moz-appearance: none !important;
  background-image: none !important;
  background-color: black !important;
}

#threadTree treechildren::-moz-tree-cell-text(selected) {
  -moz-appearance: none !important;
  color: orange !important;
}

#threadTree treechildren::-moz-tree-row(selected, focus) {
  -moz-appearance: none !important;
  background-image: none !important;
  background-color: red !important;
}

#threadTree treechildren::-moz-tree-cell-text(selected, focus) {
  -moz-appearance: none !important;
  color: yellow !important;
}

5. Restart TB.

Change the colors as desired. Tested and working in TB 68.2.2/W10.

I don't know about the arrows, as they are visible here in W10. Are they visible with the default or light themes?

I was able to create the CSS file as described here but it doesn't change anything regarding colors. However, it does uniformly make the selected message visible with a pale gray shade.

I've attached two pictures with the css applied. The first one shows the red background and yellow text of a selected message when the focus is on the Threads Pane, and the second when the focus is not on the TP. The blue text is the normal color of unread messages.

Check that your css file is of type 'Cascading Style Sheet', not Text, and that the name is exactly userChrome.css.
