Mozilla Firefox, or simply Firefox, is a free and open-source web browser developed by the Mozilla Foundation and its subsidiary, the Mozilla Corporation.

Firefox puts your privacy first — in everything we make and do. We believe you have the right to decide how and with whom you share your personal information. Firefox collects as little data as possible and never sells it. The little data we do collect is only used to make products and features better. No secrets. But a lot of transparency and real privacy.
