It has been six weeks since Firefox 3 has been released and if we believe market share numbers provided by an ongoing survey of NetApplications, then it appears that Mozilla has had a successful launch with market share gains, especially at the expense of Microsoft’s Internet Explorer.

Mozilla achieved an important milestone in November, sailing past 20% market share over an entire month for the first time since its release in November 2004. While Safari and Chrome were able to take over share from Microsoft’s Internet Explorer as well, Mozilla’s Firefox leaped by almost a full percentage point over October, according to data provided by Net Applications.

Mozilla Firefox 3, the free and open source web browser, has finally overtaken Microsoft Internet Explorer 6 and is getting closer and closer behind IE 7. According to data from StatCounter Global Stats, for the first time in February of this year, Firefox 3 with 24% market share overtook IE 6.

The latest figures from French based Internet traffic analyst XiTiMonitor shows that the Mozilla's Firefox web browser has continued to take market share off Microsoft's Internet Explorer across the globe over the past year, with a significant spike in Firefox usage in December 2007.

On the back of the release last week of Firefox 3.0, Mozilla's open-source browser gained market share at the expense of rivals Internet Explorer (IE) and Safari, Net Applications said Monday.

When Mozilla released the Firefox browser in 2004, Microsoft's Internet Explorer dominated the market with a whopping 95 percent share. Now Firefox has 18 percent of the market and Apple's Safari has another 6 percent.

A new report shows that that slide has put Internet Explorer’s market share at just under 60%.

"According to a recent comprehensive Web browser report, Microsoft's Internet Explorer is losing market share to Mozilla Firefox. The overall report shows that IE has dropped below 70 percent. [...] Each month since October, IE has dropped a point while Firefox gained a point..."

Internet Explorer has held a virtual monopoly on the mainland, home to 160 million Internet users. Now, Firefox is pushing for more market share.
