Great while it worked! I write the bugs here since in the forum of this add-on you cannot register a new user.
FF24 - does not work anymore with TreeStyleTab. All tabs below a node have the same color as the node.
It should not overwrite the settings in the usercrome.css. If you have text color settings there this add-on just overwrites them with black. It can and should change the background of the tab but not the text color of the tab.
