Firefox 69 defaults to blocking third party trackers

by Kelvin

Firefox continues to take measures to ensure privacy for users. As of Tuesday (3), the browser will by default block third-party tracking cookies and cryptocurrency miners present on websites.

Firefox Quantum


Released with Firefox 69, the solution prevents companies from creating user profiles from their internet activity and thus showing targeted ads, for example. Third-party crawler blocking has been in place since June, but was only for new browser users.

Today, 20% of Firefox users adopt blocking, which takes into account the list produced by Disconnect, a crawler protection tool. Mozilla expects now that blocking is enabled for 100% of users.

Blocking against crawlers began offering in Firefox 42, released in 2015. In that version, the browser had a simpler block that prevented ads and social buttons only in incognito mode.

In Firefox 57, released in November 2017, the option is no longer anonymous, but was not enabled by default. In October 2018, Firefox 63 was blocked against third-party tracking cookies.

Blocking these elements by default announced in Firefox 69 does not prohibit cookies from the site itself, which allow users to be logged in to their accounts, for example.

Third-party tracking protection is represented by the shield icon in the address bar. When selected, it allows you to indicate what is being blocked and create exceptions for some sites.

Protection against cryptocurrency miners

In addition to third-party tracking cookies, Firefox 69 has also blocked cryptocurrency miners by default. The elements are included on websites to favor third parties, but cause slowness and increase the battery consumption of the device.

With the new browser version, users have also been given the option to ban digital identity trackers that can capture a device's settings. The feature, however, only works when content locking is in “Strict” mode.
