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...

ਇਹ ਸਮੀਖਿਆ ਐਡ-ਆਨ (3.3) ਦੇ ਪਿਛਲੇ ਵਰਜਨ ਲਈ ਹੈ। 

Version 4.1 is compatible with Thunderbird .5* and 6.*
