Mozilla is today releasing Firefox 66 to the stable branch. Let's see what is new in this version of the popular browser.
Firefox 66 for Desktop will add support for Windows Hello authentication in Windows 10. At the time of this writing, the browser is on version 65 of the stable branch, so the Windows Hello feature will be included in the next release of Firefox that is expected on March 19, 2019.
Firefox 66 will include a new privacy option that will also block autoplay of sounds on websites. The option will be enabled by default for all users of Firefox for Android.. In Firefox for Desktop, the feature will be initially enabled in Firefox 66 for a select group of users.
Mozilla is adding a new feature to Firefox 66. Scroll Anchoring should eliminate unexpected page content jumps that happen when images and ads are being asynchronously loaded at the top of the page, making you scroll the page down.
A new feature has landed in pre-release versions of Mozilla, and it will reach the production branch soon. Firefox users will be able to assign keyboard shortcuts (hotkeys) to actions available for installed extensions.
