Hi, MinimizeToTray works great for me but it has a huge inconvenient that forced me search for an alternative: it does not save the settings and every time I restart the computer I have to enter preferences to be able to minimize Thunderbird to tray.

By the way, I am using Mozilla Thunderbird 2.0.0.22.

Any answer would be highly appreciated.
