Apple Inc. has added a do-not-track privacy tool to a test version of its latest Web browser for keeping customers' online activities from being monitored by marketers.
The tool is included within the latest test release of Lion, a version of Apple's Mac OS X operating system that is currently available only to developers. The final version of the operating system is scheduled to be released to the public this summer. Mentions of the do-not-track feature in Apple's Safari browser began to appear recently in online discussion forums and on Twitter.
The move by the Cupertino, Calif., company leaves Google Inc. as the only major browser provider that hasn't yet committed to supporting a do-no-track capability in its browser, called Chrome. Microsoft Corp. and Mozilla Corp. both offer do-not-track features in their latest browsers.
