Thunderbird 91.4.1 (64-bit) - How to add horizontal lines to messages list?

hi everyone, New Mozilla Thunderbird user and loving it. works flawlessly with Gmail Email, contacts and calendar integration.

One thing I'd like to do is add the horizontal lines in the messages thread. I searched the web for information and came across a number of threads on various forums on how to utilize the userChrome.css file with code to put in. However, none of the codes/options I tried seem to work.

Is there a way to do this in Thunderbird 91.4.1 (64-bit version)?

Thank you

Try this:

#threadTree treechildren::-moz-tree-row {
  border-bottom: 2px solid threedlightshadow !important;
}


Help/More Troubleshooting, 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 number as desired. Double-click toolkit.legacyUserProfileCustomizations.stylesheets to true in Preferences/General/Config. editor, restart TB.

Thank you. That actually worked. i think the step that all the other forums I found didn't mention anything about the Config editor option.

Another question.. is there a way to make it so the messages alternative colour within the messaged list thread?

Thank you SO much. Just what I needed. I was able to mix both entries into the same .css file and get the results needed.
