Mozilla has launched Firefox 70 for Windows, Mac, and Linux with new features such as social tracking protection, a Privacy Protections report, and a native data breach notification service for your saved logins.

The company — which began offering granular control over third-party tracking last October with Enhanced Tracking Protection — has now added social media trackers to the mix. This will block all trackers associated with Facebook, Instagram, WhatsApp, Twitter, LinkedIn, and YouTube.
