Google says it's making progress on plans to revamp Chrome user tracking technology aimed at improving privacy even as it faces challenges from regulators and officials.

The company gave an update Monday on its work to remove from its Chrome browser so-called third-party cookies, which are used by a website's advertisers or partners and can be used to track a user's internet browsing habits.

Third-party cookies been a longtime source of privacy concerns and Google said a year ago that it would do away with them, in an announcement that shook up the online advertising industry.

The changes will affect Chrome, the world's dominant web browser, as well as other browsers based on Google's Chromium technology such as Microsoft's Edge. Rival browsers Safari and Mozilla Firefox have already removed third-party cookies by default but Google is taking a more gradual approach.
