In addition to supporting Firebug, we're also experimenting with alternative developer tools.
It's my belief that most developer tools just present the user with the information that was given to the browser in the first place, and that we can do a lot to explain how the browser actually understands all that stuff. The native developer tools are a step in that direction.
I work on Mozilla developer tools.
Sure, Mozilla supports the development of Firebug, but as far as I know it does not make Firebug classified as "a Mozilla project", it's a (very popular) third-party project with support from the Mozilla foundation is it not?
