This IRC client has one of the best interfaces I've seen. It's customizable with its CSS, and the light motif looks great, especially with adjustments to the fonts. Adding tabs to auto-join a server and/or channel on startup is a breeze, and chat logging is easy to set up (and outputs to human readable plain text files). Colors and highlighting make each type of activity very easy to distinguish, and the flashing taskbar button is a great way to keep alert about mentions of your name or any selected keywords for notification.

My only two gripes would be that a.) You can't restart Firefox without restarting Chatzilla, which means that if you want to use Chatzilla uninterrupted, your Firefox memory usage will slowly build up; and b.) the flashing orange taskbar button in Windows is equivalent to a bouncing Firefox icon in the Mac OS X dock, which is a bit less helpful (as it's not immediately clear whether it's about Chatzilla or some other Firefox process grabbing attention). It'd be wonderful if Chatzilla could somehow work with the Growl application or somehow have its own Chatzilla icon representation on the dock.

I like using CZ very much, but the only thing that I with it had was a "Welcome Back," or "WB," ability. mIRC has that ability and I have found that it is used a lot in IRC. This would be a great thing to have on ChatZilla for those who don't know JavaScript.

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.
