Later - in November 2017, with Firefox 57, aka 'Quantum' - Mozilla expanded Tracking Protection to cover non-private browsing. But there was a problem with stymying this cross-site tracking: When switched on, Tracking Protection often broke sites. Originally called just 'Tracking Protection' and restricted to Firefox's private browsing mode, the technology blocked a range of content, not just online advertisements but also in-page trackers that sites or ad networks implanted to follow users around the web. A short history of ETPĮnhanced Tracking Protection was the main attraction to the update - according to Mozilla's numbering system, a minor one at that, what with version 67 debuting weeks ago - if only because the developer has long talked about the feature. Mozilla also used the update to Firefox 67.0.1 to trumpet other privacy- and security-centric enhancements, including an add-on that brings its Lockwise password manager to the desktop browser and an improved Facebook Container, an extension designed to keep the social network behemoth from tracking users elsewhere on the web. The default-of-on will be extended to those users 'in the coming months,' Mozilla said, apparently activating it in stages as a last-step quality control. Existing customers simply updating their browsers may enable ETP themselves. With a June 4 update to Firefox 67, Mozilla turned on Enhanced Tracking Protection (ETP) by default for new users.

Mozilla this week began to switch on an aggressive anti-tracking technology in Firefox that it has touted since 2015.
