Initiall I installed this addon on T3, but the new mesasge counter doesn't update after marking messages as read. So need to uninstall it and install v2.8.
But later upgraded Thunderbird to 5 and installed v3 on it, and it works fine.
The new version is not backward comaptible, but it works well on latest.
