Google, Mozilla Announce Do-Not-Track Browser Options

摘要

Google, Inc., on Jan. 24 announced the availability of a do-not-track feature for its Chrome browser that allows users to opt out permanently from cookies used by participating companies for targeting personalized ads. Meanwhile, Mozilla Corp. on Jan. 23 proposed a new Firefox browser preference setting that would inform participating websites of the user's desire to opt out of online behavioral advertising. Both Google and Mozilla said, in blog postings by company officials, that the new features would be more persistent than the advertising industry's cookie-based approaches, which don't survive the clearing of a browser's cookies.
