This is a fork of foudfou/FireTray
The original FireTray has been patched to display the number of unread messages in KDE/Windows system tray.
It is a workaround for issues:
To build XPI file just do: cd src make build
To install icons on Kubuntu: cp ./src/chrome/skin/icons/unread/.svg /usr/share/icons/breeze/actions/16/ cp ./src/chrome/skin/icons/unread/.svg /usr/share/icons/breeze/actions/22/ cp ./src/chrome/skin/icons/unread/*.svg /usr/share/icons/breeze/actions/24/
