userChrome code for not empty?

Postby Anonymosity » Mon 14 Dec, 2009 4:27 pm

Is there any stylesheet code that can specify a folder being not empty? I was trying to get the Deleted (Trash) folder in the email accounts to change colour when it has any content in TB3, and I have been unable to find anything about distinguishing empty folders from non-empty ones. There must be a way to do that. TB2 used to do that with the Deleted folder, but TB3 does not.
