You can still make it work in Thunderbird 5 as previous comments have stated, but it causes a bug in the status bar at the bottom, where everything vashes, except number of messages unread & total - even with all other addons disabled. Have to disable it until there's an update as I need my status bar...

This review is for a previous version of the add-on (3.3).

I haven't tried this version, but the 0.0.5 you can download from the help link :

Just installed it with thunderbird 2.0.0.22 and so far haven't seen any errors, and it does what it promises, on folders containing several thousand emails. Been looking for this for a while. 5 stars from me!
