Hi, I'm new to Firebug and wanna to port Firebug for some malicious javascript analysis. Are there any documents talking about the internal of Firebug,especially about the architecture,design of Firebug?

Thanks

You can read my "How to build Firebug extensions" tutorial that explains Firebug architecture pretty well:
