The report from NetApplications.com says over July, Microsoft's Internet Explorer gained 0.6 percent from 86.6 percent in June to 87.2 percent in July. While Firefox's share decreased from 8.7 percent in June to 8.1 percent in July.
Over the course of this year, Firefox had posted monthly market share gains of between 0.5 percent and 1.0 percent at the expense of IE, according to NetApplications.com, which compiles its browser usage data from more than 40,000 websites monitored by its HitsLink.com service.More details at TechWorld.
Apple's Safari ranked third and grew its share slightly to 2.13 percent from 1.93 percent, while Netscape, which once ruled this market, slid a bit to 1.50 percent from 1.55 percent. Opera came in fifth with a 0.49 percent market share.
I believe when Microsoft launches Internet Explorer 7, Firefox's marketshare will continue to drop.
