The desktop and mobile version of Firefox 59 and Firefox ESR 52.7 released.
Firefox 59 has performance enhancements that should lead to faster load times, new search engine options for German and French users, and a change in Firefox Private Browsing Mode to prevent cross-site tracking.
The releases also come with security updates, which include memory safety fixes, which could lead an attacker to run arbitrary code.
During the week, Mozilla said starting with Firefox 62, support for device orientation, motion, proximity and ambient light events will be deprecated in an effort to protect user privacy.
The (now obsolete) APIs for proximity and ambient light will be disabled by default, but users will be able to enable them by typing about:config in the browser’s URL field, finding the device.sensors.enabled value and setting it to false.
