BILLIONAIRE FREE FOR 20+ YEARS
The Firefox browser was created in 2004 by Mozilla as a faster, more private browser with more customizable features than web browsers like Internet Explorer. Today, we are still not-for-profit, still not owned by any billionaires and still working to make the internet — and the time you spend on it — better.
