Both Firefox and Chrome browsers have updated with security and privacy updates. Firefox added an Enhanced Tracking Protection feature that blocks third-party sites that track users. Chrome added a beta Reader Mode that distills a page down to what Google assumes is the featured text and art. Chrome also added an on-the-fly password manager to the Android OS version of its browser. Firefox also updated its Facebook Container (now 2.0) browser extension for desktop users.
