HashColouredTabs+ For Mac Publisher's description
from John P Baker
A Firefox add-on that improves tab identification
Improves tab identification by providing a small colored icon for any site which doesn't have its own 'site icon'.
HashColouredTabs+ extension is a modified version of the Terry Yuen's HashColouredTabs.; It will now also show the coloured icon in the location bar, the 'List all tabs' dropdown (Firefox 2), History Sidebar and menu, Bookmarks Sidebar and menu, urlbar autocomplete results, and the back/forward dropdown (Firefox 3).
