Thunderbird Minimize To Tray extension

I just found an updated version of the MinimizeToTray extension for Mozilla Thunderbird that works with v1.5.

The extension does exactly what you’d think from the name – allows Thunderbird to be minimised to the system tray in Windows rather than staying in the task bar when minimised. This means I can have mail running all the time without it cluttering up the UI – and it’s easy to recall when I need it.
