CloseReview for MinimizeToTray revived by martensite
Rated 5 out of 5 stars
Great add-on ! As it was said before, this feature should be implemented in thunderbird options.
But since last thunderbird update (52.1.1), MinimizeToTray only minimizes thunderbird to tray when minimizing window but not when closing window (it quits thunderbird instead). I only tried on linux installs (ubuntu and archlinux).
