The Mozilla Corporation ("MoCo"), which develops Firefox, is a wholly owned subsidiary of the non-profit Mozilla Foundation ("MoFo"). Each has its own board of directors, but the Corporation exists to serve the public benefit goals of the non-profit. The link above has a decent overview, and if you're especially curious, bylaws and articles of incorporation for each are at https://www.mozilla.org/en-US/foundation/about/.
