In my first job, about four years ago, my first task was to make certain modifications in firebug for our company's internal use (mostly in reporting and filtering). I didn't even know JS to begin with. Jan Orvadko, the lead maintainer of Firebug, is an amazingly approachable & affable human being. He helped me a lot in the IRC channel, in going through the firebug codebase.
