Mozilla has announced that the latest version of its Firefox browser will allow users to choose if they prefer to block online trackers, which follow internet users from site to site. The new tool, called “Tracking Protection”, will be implemented into the Firefox Private Browsing (which until now has only managed locally stored content), for the purpose of deleting cookies whilst allowing third-party scripts to run as intended on the site.

Under the browser's new setup, the Private Browsing mode will block any script that could be used to identify a user, including ads, analytic trackers, and features, such as the Facebook Like button that can be tied back to social networks. The result is a more anonymous kind of browsing that will load pages faster and cut off advertising networks. Users will have the option to turn it on or off, as they do with Private Browsing.

This decision follows the trend of improving the users’ control over the data and content presented to them, as we reported in our recent client updates. Very recently, Apple iOS 9 introduced similar changes which allow users to use Content Blocking Safari Extensions on their iPhone apps, which block cookies, images, resources, pop-ups, and other content.
