Hi, is there a way to get Thunderbird to move to the tray when I press the X button in the top right corner? I've tried enabling "When Thunderbird is minimized, move it to the tray" but that just changes what the minimize button does. When I press X, Thunderbird still quits. I've done some googling and I found this extension: https://services.addons.thunderbird.net/en-US/thunderbird/addon/minimize-on-close/ The problem with it is: # It doesn't seem to work with modern versions of Thunderbird # It lets you either minimize the window '''or''' move it to the tray, but not both (X and minimize do the same thing) Can I get Thunderbird to close to tray '''only''' when I press X? So that the minimize button still works normally? Thanks
