Historical Firefox Statistics

Firefox muscled its way past several established browsers to build its loyal user base. Here are Firefox’s most important milestones and facts since its inception.

11. Firefox was first released in 2004 but traces its roots to the 90s.

As a fully-fledged browser, Firefox’s first public release was on November 9, 2004. However, it can trace its roots through the Mozilla Project to Netscape.

The Mozilla Application Suite was initiated by Netscape in 1998 as a suite of tools containing the main Netscape Navigator browser, Communicator (Newsgroups and Email), a Web page maker (Mozilla Composer), and an IRC chat client (ChatZilla).

Mozilla eventually phased out the original Navigator code and although it survived an initial acquisition from AOL, went its separate ways in 2003 when AOL partnered with Microsoft and Internet Explorer instead.

12. There were two different names before the browser became Firefox.

Before Mozilla settled on the Firefox name, the project started life as Phoenix. This was a reference to rising from the ashes like a phoenix from its spiritual predecessor Netscape. However, following a trademark claim from Phoenix Technologies it became Firebird.

This too was seen as an infringement on the Firebird database project, so it eventually became Firefox in early 2004, ahead of its public release.

13. In its first year Firefox received over 100 million downloads.

Although not everyone adopted it as their default browser, within its first year of being released Firefox had over 100 million downloads. This was partly down to a successful Spread Firefox campaign pushed by developers and early adopters.

14. Firefox began performing better than Internet Explorer in 2006.

Although its initial releases suffered from high memory usage, Firefox began outperforming Internet Explorer in 2006 with Firefox 2.0 and Internet Explorer 7. This raw performance success would continue into the 2010s as IE began to decline in popularity.

15. Firefox’s most popular year was 2010.

It would take around five years before Firefox would reach its peak in popularity. This occurred in 2010 when it held approximately 32% share of the global browser market. With the introduction of Chrome and the rise of mobile browsing, its share would gradually drop as the years went on.

Chrome would surpass Firefox in 2012, while Firefox would surpass Internet Explorer in 2015 in a race to the bottom.

16. Google searches for Firefox peaked in 2008.

Although Google doesn’t reveal precise numbers, its Trends data shows the highest interest for the search term Firefox occurred in June 2008. This the same month Mozilla unveiled Firefox 3, which created a huge buzz online.

17. Firefox integrated its own VPN service in 2020.

After a beta phase, Mozilla launched a VPN service in July 2020, which offers a limited free version as a Firefox extension. The premium version is available across desktop and mobile devices and is supplied by the Swedish-based Mullvad VPN.

Financial Firefox Statistics

These stats take a closer look at Mozilla’s revenue and other interesting financial data related to Firefox.

18. Mozilla reported revenues of $600 million in 2021.

The last time Firefox’s parent company Mozilla issued an annual financial report was in 2021, when it recorded revenues of $600.68 million.

This was a decline from 2019’s $826.6 million but up from 2020’s 496.86 million figures.

19. Mozilla’s overall assets are worth more than $1.2 billion.

Including Firefox, all Mozilla projects, products, and assets are worth a total of more than $1.2 billion as of 2021.

20. Firefox has two main revenue sources: search engine royalties and advertising revenue.

As a free browser, Firefox earns the majority of its revenue through partnered search and ad revenue. When a user chooses one of the built-in search options, Mozilla gets royalties as a percentage of revenue generated by that search.

Firefox also serves ads directly through sponsored content when new tabs are opened and via its Pocket email service.

Furthermore, the relatively new Mozilla VPN service saw a revenue increase of 450% from 2020 to 2021.

21. Mozilla is investing in “trustworthy” AI and machine learning.

Unlike Microsoft Edge with Bing Chat and Opera with Aria, Firefox has yet to implement an AI assistant directly within the browser. However, that may change as Mozilla Foundation CEO, Mitchell Baker, recently said: “It’s time to bring our public benefit-driven mindset to products rich with machine learning and the power of new technologies.”

Earlier this year, the foundation launched Mozilla.AI, which is focused on building AI that’s open source and “trustworthy.”

Conclusion

In 2023, Firefox remains a competitive web browser that takes a transparent approach to its features and user privacy, in a market dominated by giants like Google, Microsoft, and Apple.

Although it’s not the most popular, it has a loyal user base and is quickly researching AI, which could lead to similar or better features than have already been implemented by Edge and Opera.
