Google (GOOG) on Tuesday released an update for its Chrome Web browser for Windows, Mac and Linux computers that finally brings support for a “Do Not Track” option. Chrome was the last major browser to support the feature and had previously forced its users to rely on third-party extensions. When enabled, the Do Not Track protocol blocks tracking cookies used by advertisers for targeting purposes. The latest version of Chrome also delivers increased battery life to Windows users due to Google’s new GPU-accelerated video decoder, which is said to increase battery life by as much as 25% compared to earlier Chrome versions. The Web browser is rolling out now to current Chrome users and can also be downloaded from Google’s website.
