I am on Windows 10, Thunderbird Version 91.5.0 64 BIT

I have looked in the various threads that cover this particular issue, Most of the addons are not compatible with my version.

after looking around, I stumbled on some changes to the userChrome.css file that should work.

The first part of the css file, changes backwound colors. This works

the part is not working is what I assume will change the font and its size.

I would appreciate any help...

#folderTree,

  1. threadTree

{

 background-color: lightgrey !important;
 color: black !important;

}

/* Folder Pane font */

  1. folderTree > treechildren {
 font-size: 18pt !important;
 font-family: Verdana !important;

}

/* Threads Pane font */ .tree-rows {

   font-size: 18pt !important;
   font-family: Verdana !important;

}
