Instabird is the newest project from the Mozilla folks, and it’s a multi-client chat program that allows you to connect to several of the mainstream instant messaging services such as AOL, MSN, and Yahoo!. The project is still in early beta (version .1 beta), but the adventurous user can strike out and attempt to compile a copy of their own. That’s right, I said compile.
The download weighs in at only 13.1 megabytes, which should be quick on most broadband connections, and for Windows users, the install process, while not the prettiest in the world, is relatively painless and took about 45 seconds or so (as opposed to the reported two hours it can take to compile on Ubuntu). I was able to connect to all my accounts error-free, and was chatting within five minutes of my download completing.
The user interface of Instantbird is written in XUL. Therefore you can write extensions for Instantbird like you can do for any other XUL application (Firefox, Thunderbird, etc...). You will find much useful information on the Mozilla Developer Center.
