While the add on does indeed show the list of Favourites when Thunderbird starts, as soon as you access one of these folders, the view changes back to the All Folders view, although the label of the block still says Favourite Folders. This makes the app. all but useless. This needs to be fixed before it can work properly. If it is fixed this will be a great app. but at the moment it is worthless.
