Who Owns Firefox, The Popular Web Browser?

Regardless of your preference, certain web browsers are easily identifiable by the companies behind them. Google Chrome, which had several new features released in 2026, is run by Alphabet Inc., and it goes without explanation who runs Microsoft Edge — the browser that succeeded Internet Explorer after almost 30 years. Certain internet users may be unaware, however, who the operating entity is behind another popular browser — Firefox. Its full name — Mozilla Firefox — reveals more about its roots and parent company. The browser, which launched in 2002, was developed by the not-for-profit Mozilla Foundation. 

This foundation is a non-profit organization built on the principles of what it calls the Mozilla Manifesto, which was drafted in 2007. Per the Manifesto, the company aims to "articulate a vision for the internet that Mozilla participants want Mozilla Foundation to pursue." The stated goals go on to say that Mozilla's work should make sense to those who use it, regardless of technical background, and that it should be considered a framework for others to lean on when it comes to the overall vision of the internet.

The Mozilla Foundation and Mozilla Corporation — the entities behind the Firefox web browser — are responsible for more than their signature product. While the company has been recognized for accomplishments like a Firefox AI setting that every browser needs, Mozilla has also produced offshoots including Firefox Focus — a private mobile browser — and Firefox Relay — a service intended to protect your identity via email and phone masks. Other, non-Firefox services Mozilla offers include Thunderbird — a productivity app designed to consolidate emails, calendars, and contacts into one efficient space. 

The organization also provides Mozilla VPN, which affords users access to 500 servers in over 30 countries with up to five devices. Solo, a website builder, implements code-free web design, SEO features, and simple transitions between desktop and mobile versions, aimed at helping businesses expand their platforms. Mozilla has also followed suit with other tech companies and invested in AI through software like 0DIN — a service which enables users to test their chatbots and AI agents against real attacks as a way to provide data for security and risk teams. These, among other programs, show Mozilla is not a one-trick pony with Firefox, and remains dedicated to its vision of inspiring users and advancing the internet.
