The BBC reports that Firefox recently passed its one billionth download. The BBC says Firefox has 31% of the worldwide browser marketshare and Microsoft's Internet Exporer has 60%.
Figures suggest that Firefox now has nearly one third of the browser market worldwide, at 31%.
Microsoft's Internet Explorer still dominates the field with around 60%, whilst Google's Chrome, Apple's Safari and Opera are all less than 5%.
Microsoft is currently in talks with the European competition regulators, which ruled in January that pre-bundling Internet Explorer with the company's Windows operating system hurt competition.
Mozilla encourages people to spread the Firefox browser through its Spread Firefox website. They have also set-up a website celebrating the 1 billion downloads.
