Firefox adds tracking protection by default

The Mozilla blog announces
a new Firefox feature: 'One of those initiatives outlined was to
block cookies from known third party trackers in Firefox. Today, Firefox
will be rolling out this feature, Enhanced Tracking Protection, to all new
users on by default, to make it harder for over a thousand companies to
track their every move. Additionally, we’re updating our privacy-focused
features including an upgraded Facebook Container extension, a Firefox
desktop extension for Lockwise, a way to keep their passwords safe across
all platforms, and Firefox Monitor’s new dashboard to manage multiple email
addresses.'
