Who Owns Firefox?
Firefox is owned by Mozilla Corporation, the for-profit subsidiary of the nonprofit Mozilla Foundation. The browser launched in November 2004 from the open source project that grew out of Netscape and remains one of the only major browsers not built on Google's Chromium engine. Mozilla reported $680 million in consolidated revenue in 2024, most of it tied to Firefox's search partnerships.

History of Firefox
- Founded: 2004
- Founders: Dave Hyatt, Blake Ross
Firefox descends from Netscape Navigator. When Netscape open sourced its browser in 1998, the Mozilla project formed to build the next generation. After years developing the bloated Mozilla Suite, engineers Dave Hyatt and Blake Ross started a stripped-down browser-only project in 2002 under the name Phoenix.
Trademark conflicts forced two renames, to Firebird and then Firefox, before version 1.0 shipped on November 9, 2004. A community-funded two-page ad in the New York Times announced the launch. Firefox took double-digit market share within a year, peaked around 30 percent in 2009 to 2010, and was credited with ending Internet Explorer's monopoly.
Chrome's 2008 launch started a long decline in Firefox's share as Google tied distribution to its platforms and Android. Mozilla responded with the Quantum engine overhaul in 2017, a major speed and architecture rewrite, and steady privacy features including Enhanced Tracking Protection and Total Cookie Protection.
In the 2020s Firefox has repositioned around privacy and independence. The 2024 to 2026 roadmap added AI features under user control, expanded mobile extensions, and maintained the Gecko engine as the principal non-Chromium alternative as antitrust actions pressured browser defaults.

The brand's visual identity evolved alongside. The flaming fox wrapped around a globe, introduced at launch and redesigned several times, most recently in 2019 and 2023, became one of the most recognizable logos in software. Mozilla also developed sub-identities for Firefox on iOS, Android, enterprise deployments and the Focus privacy browser, all feeding back to the same Gecko-engine family on desktop.

Firefox Recalls & Controversies
Mozilla faced criticism in 2021 for briefly accepting cryptocurrency donations and in 2024 for laying off advocacy staff. A 2024 debate over terms of use language requiring a license to process user data prompted Mozilla to clarify that Firefox does not claim ownership of user content. Periodic reports of declining market share drive recurring scrutiny of the Google search dependency that funds the browser.
