> Anybody got the breakdown on community commits to FF vs. employee commits?

Last time I saw anyone try to do this, it was vastly predominately employee commits (this isn't that surprising, there are hundreds of people working full-time on Firefox at Mozilla, and very few spending a comparable amount of time per day in the larger community); it's hard to get exact numbers because determining whether a commit is by an employee or not is hard (e.g., there's no requirement for employees to use Mozilla email addresses for their commits).
