Firefox is maintained by the Mozilla Corporation, a wholly-owned subsidiary of the Mozilla Foundation. While Firefox does produce revenue — chiefly through search partnerships — this earned income is largely reinvested back into the Corporation. The Mozilla Foundation’s education and advocacy efforts, which span several continents and reach millions of people, are supported by philanthropic donations.
Firefox 由 Mozilla 公司（Mozilla 基金会的全资子公司）维护。虽然 Firefox 的确带来收入（主要来自搜索引擎合作伙伴），但这笔收入的大部分将被重新投资到公司中。Mozilla 基金会的教育和宣传工作覆盖数个大洲的上百万人，这些工作由慈善捐助支持。
