How do I change Thunderbird's display (Menus, folders, toolbars etc.). The fonts are way too small for reading. I am talking about the menus, toolbars and folders.

For the Threads and Folder Panes, use this code: 

.tree-rows
{
  font-size: 16px !important;
}

For the Menu Bar and submenus: 

/* Menu Bar font */
menubar > menu
{ font-size: 18pt !important;
}

/* Submenus and context menus font */
menupopup,popup {
    font-size: 12pt !important;
}

Help/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 numbers as desired. Double-click toolkit.legacyUserProfileCustomizations.stylesheets to true in Options/General/Config. editor, restart TB.
