Firetray

Overview

Js-ctypes rewrite of the binary XPCOM version of Firetray.

for all applications:
- show/hide a single or all windows
- a window gets restored to its previous state, position, size, virtual desktop
- optional hide to tray on minimize
- optional start minimized to tray
- optional show icon only when hidden to tray
for mail applications:
- display unread messages count in tray icon
- customizable tray icon for mail biff
- include/exclude mail accounts and folders types to/from unread messages count

Firetray unsets the tabs.warnOnClose built-in preference, which otherwise disrupts the handeling of the close event.
Experimental non-customizable keyboard shortcut for hiding all windows set to: accel-shift-w

if you're looking for other mozilla-desktop integration:
- Paul Neulinger's Gnome-shell-Thunderbird integration
- Mike Conley's Unity-Thunderbird integration
- discontinued Mozilla New Mail Icon (Biff)
Alltray launches any applications into tray

windows aren't restored with the same z-order, but there is no means to correct that under Linux
notifications for excluded mail account servers are not disabled. Newmailalerts are hard-coded and we can't easily disable thme on a per-server basis (only globally, see mail.biff.show_alert). The proper way would probably be to disable default notifications globally, and handle notifications ourselves. This is out of the scope of this addon, but you may want to give a try to the MailAlert extension
