It's the opposite. It's the Mozillq Corporation that develops the browser. The nonprofit Mozilla Foundation, which owns the corp, does not. You can donate to the nonprofit, but you can't donate to the corporation. Furthermore, what a lot of people dislike is that the foundation's money doesn't go towards Firefox development. Instead, Firefox revenue (almost entirely royalties from Google) are passed by the corp to the foundation.
