"Poor Microsoft. This week, the Redmond, Wash., giant is gearing up for the next big release of its Web browser, a leap from Internet Explorer 7 to IE 8. When open-source competitor Mozilla released its last update of Firefox in June, the Web went wild: People downloaded more than 8 million copies in 24 hours. Microsoft's release might not have such a frat party feel. Even as it gears up to release IE 8, the developers behind the Firefox Web browser are experimenting with a new technology that sharpens the threat their browser software poses to Microsoft's most valuable businesses. The new technology, dubbed TraceMonkey, promises to speed up Firefox's ability to deliver complex applications." While many have abandoned Microsoft's browser offerings, Microsoft will be introducing an innovative new type of selective privacy mode called InPrivate with IE8.
