Instantbird is a new instant messaging application that merges two powerful open source projects: XULRunner, the stand-alone version of Firefox browsing engine; and libpurple, the library that gives Pidgin its ability to connect to most of the existing instant messaging networks.
The first development release, 0.1, provides the very basic functionality of what we have come to expect from an instant messaging application. On first run, an account wizard pops up to add your first IM account from any of the 16 networks libpurple supports. Enter your username, password and you are good to go.
