Thunderbird - quit when close When I close the windows of Thunderbird 38, it is because I have finished to work on my mails.
But Thunderbird is still running and can tell me when new mails are arrived. 

For now, I have to click-right on Thunderbird to quit.

Is there a way to quit Thunderbird when I close the window?

I am using Mac OSX 10.10.
No, as on Macintosh closing Applications' windows ( by either clicking on the top-left red button or doing Command+W ) doesn't quit it. 

To quit it, instead of closing all windows, you have to actively go into the menu option through [Application Name] / Quit [Application Name] or by doing Command+Q
