Change Specific Folder Color For New Mail?

I am trying to prevent an inbox folder for a particular email account from turning bold and blue when it receives new and unread messages. So far I have found solutions that apply to ALL folders but nothing to specify a particular folder-name? Examples: /* Highlight Folders if subfolders have unread messages */ treechildren::-moz-tree-cell-text(subfoldersHaveUnreadMessages-true) {

 color: red !important;

}

/* Make Folders having Unread_Messages distinct from others */ treechildren::-moz-tree-cell-text(hasUnreadMessages-true) {

 color: blue !important;

}

/* Change Folder Display to indicate New Message(s) arrived */ treechildren::-moz-tree-cell-text(folderNameCol, newMessages-true) {

 color: red !important;
 font-weight: bold !important;

}

I see you are having quite a discussion on the topic of CSS here https://support.mozilla.org/en-US/questions/1333072

As CSS is technically beyond the scope of this forum I suggest you continue the discussion with th like minded individual you have already found or try asking in developer forums.

I tried to get into the developer chat but there are all sorts of errors when trying to do so, appears to be setup as more of a chat than a forum?
