John Lilly, the new CEO of Mozilla Corporation, doesn't want you to pay attention to his new charge. The for-profit arm of the nonprofit Mozilla Foundation produces the Firefox browser and makes money largely by partnering with search engines — that's why the Firefox browser comes with a Google or Yahoo search box built in. "The most successful case for [Mozilla Corporation] will be when the corporation itself is sort of invisible," Lilly writes. Now, why would Lilly want you not to pay attention to his very profitable business — $66.8 million in revenues for the foundation, $56 million of which came from the corporation, in 2006, the most recent year for which it reported results? Perhaps it's because there are questions he'd rather you not ask.
