CloseReview for Minimize on Close by dkwalton
Rated 1 out of 5 stars
Works fine in conjunction with Thunderbird's native setting to minimize to tray and a Windows startup folder shortcut set to open Thunderbird minimized.
Only one star because this extension lacks a critical feature -- a right click on the tray icon to pop up a menu with an exit option in order to easily and quickly shut down the program.
