Rated 1 out of 5 stars

People don't pay much attention to how something works, do they? The point of the add-on is to
Dave_B_H:
"Using the X button only closes the window, and the program continues to run in the background, hidden. For those of us who use a pre-processing program, completely exiting is a must, or Thunderbird grabs the mail before it is processed."
My case
I using Exit Button Thunderbird 0.5, then TB only closes the window, and the program continues to run in the background, hidden.
Only Task Manager can stop it.

This review is for a previous version of the add-on (0.5).
