“It's a huge achievement by the global Mozilla community, one that just a few years ago most would have considered impossible. The open web is more vibrant than ever, and the thousands of Mozilla contributors around the world have played a major role in making it that way.”
Apple’s Safari browser was used by over seven per cent of internet sessions.
The company suggests that Firefox gained market share due to a variety of factors. Since it is used primarily in the home rather than in corporate environments the Thanksgiving holiday season will have helped Mozilla’s use.
However, Net Applications also suggests that higher unemployment may also be helping Firefox, since more people are browsing from home rather than from the office.
