Firetray

Overview

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

for all applications:
- show/hide a single or all windows
- restore windows to their previous state, position, size
- restore each window to its original virtual desktop/workspace
- activate restored windows
- hide to tray on close
- hide to tray on minimize
- start minimized to tray
- show icon only when hidden to tray
- mouse scroll on tray icon shows/hides
- GTK-themable icons
- customizable tray icons
- popup menu (show/hide individual windows, open new windows, quit)
- command-line -firetrayShowHide option (useful for window manager's keyboard shortcuts)
- command-line -firetrayPresent option (activates windows)
- middle click on the tray icon activates last registered window
for mail applications:
- display unread message count in tray icon
- display biff in tray icon for new messages
- include/exclude mail accounts to/from messages count
- include/exclude folders types to/from messages count
- count in sub-folders recursively
- handle Exquilla accounts
- restrict message count to favorite folders
- trigger external program on message count change
for applications embedding chat (currently only Thunderbird)
- display additional system tray status icon

requires GTK+ 2.20 and higher.
Firetray temporarily unsets:
- the tabs.warnOnClose built-in preference, which otherwise disrupts the handeling of the close event
- mail.biff.show_tray_icon for mail applications
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 them 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
child windows (compose message, preferences, ...) are not handled by Firetray. For ex., they are not hidden along with there top-level window.
because of getNumNewMessages()'s strange behaviour, it's impossible to display an accurate count of new messages. The best we can do is display a biff icon.
POP users should set [http://kb.mozillazine.org/Thunderbird_:FAQs:_Automatically_Download_Messages](Automatically download new messages) to see new message. See this discussion.
some features do not work well under Unity/Compiz.
