> I don't understand how Mozilla has over a thousand employees

The figure is pretty much correct. To put things in perspective, though, only a fraction of those thousand people work on the actual browser. And, of that fraction, an even tinier number work on the rendering engine.

The Chrome team, on the other hand, has pretty much the same number of people of the entire Mozilla (or MoCo, to be specific) but almost all of them work on the browser/rendering.
