According Aliso Viejo, California-based Net Applications' January 2007 report, Mozilla Firefox has lost browser market share (from 14% to 13.7%) while Apple's Safari has grown in browser usage (from 4.2% to 4.7%). For Firefox, this is the first dip since May 2006. "It appears to be a real dip," not a statistical anomaly, said Vincent Vizzaccaro, Net Applications' executive vice president of marketing and strategic relationships. Partly based on the open-source Konqueror, Safari previously held 3.1% of the browser market – its growth could indicate a slow but steady increase in Macintosh sales. "The more interesting trend is on the Safari side. It looks like it's taking share away from browsers in the Windows environment," said Vizzaccaro. Windows XP still has an overwhelming lead in operating systems, however, with 85% (Vista was at a mere 0.2% since by then it had only launched to businesses). Microsoft's Internet Explorer accounted for 79.8% of the browser market in January.
