November 9th marked the 21st anniversary of Firefox 1.0. In 2004, it was the first stable release of Mozilla’s new browser, which quickly positioned itself as a simple and secure alternative to Internet Explorer . Initially, it boasted tabbed browsing, pop-up blocking, a flexible extension system, and intuitive privacy settings, quickly attracting both the public and the press.
Before its release, the browser underwent several name changes. The experimental branch of the Mozilla Suite was initially called Phoenix , then Firebird , and, in February 2004, Firefox . It was chosen for its uniqueness and lack of conflict, and the red fox became its mascot.
The launch of version 1.0 was accompanied by a rare fan advertising campaign at the time. The community raised funds for a full-page ad in the New York Times, and on launch day, rave reviews praised its speed, usability, and compatibility with IE websites . The campaign helped make Firefox a product visible beyond the fan base.
In the years that followed, Firefox became a real force in the market. In 2008, the launch of Firefox 3 was celebrated as Download Day, with a world record for the number of downloads in a single day, over 8 million installations. Statistics at the time showed the browser was steadily gaining market share over Internet Explorer, with some reports in Europe approaching a third of the market.
The release of Firefox Quantum in 2017 marked a major technological upgrade, significantly accelerating performance and revamping the interface. In terms of privacy, the project advanced the industry with Tracking Protection enabled by default and Total Cookie Protection, which isolates cookies across websites. These solutions cemented Firefox’s reputation as a browser for users who value control and data independence.
Today, Firefox remains the only major independent browser to use its own Gecko engine, independent of Chromium. The story of version 1.0 is an example of how community and open development can shift the balance of power and how privacy and open standards can become a competitive advantage.
The 2004 release made all of this possible, hitting a raw nerve at the time and bringing competition back into the browser market.
