Firefox, Mozilla's most successful web browser based on the Gecko browser engine holds more than 20% of the web-browser market share, according to the latest figures by NetApplications placing it at 21.34%. Web browsers such as Mozilla Firefox and Apple Safari have been on a roll in the past 24 months, at the expense of Microsoft Internet Explorer (MSIE) which has been falling in market-share from the 90+ percent it once held.

Mozilla's CEO John Lilly calls this as a significant milestone for Mozilla, and gives credit to the global Mozilla community. NetApplications gets into the details of how Firefox gained a market share growth of 20%, by attributing it to the relatively high number of public holidays between November and December, when users accessed internet from home. This since the significant movers were noted to be home/domestic users rather than corporate users.
