After looking for a good open source/free software IRC client for Windows I found ChatZilla, I do web apps development, so I always have a Firefox window open. ChatZilla lacks some features we can find on mIRC or other popular IRC clients, but as I am not in IRC chatting just for fun, I amd there to get help and to help others, ChatZilla givs me all that I need and best of all it is open source, if I ever need some special feature I can do it myself.
Cheers and go ahead with this extension.
