35.4% versus 34.9% Those numbers are cause celebre for every open source advocate and Microsoft hater across the globe. According to the most recent set of browser usage statistics from W3Schools, Firefox has captured 35.4% of the browser market as compared to 34.9% for Internet Explorer version 6. As exciting as this news is, the trends show that it was only a matter of time before Firefox took the lead in the race between the two most widely deployed browsers in the world. Is Microsoft concerned? Probably more than they would ever admit. Regardless of the viability of these statistics, the Firefox development team deserves some major kudos for bringing some much needed competition to the web browser space. How worried should Microsoft be about their declining marketshare and how satisifed should the Mozilla Foundation be with their growth? Let us know what you think in the comments.
