72.0beta
Firefox Beta

December 3, 2019

Version 72.0beta, first offered to Beta channel users on December 3, 2019

New

  • Firefox’s Enhanced Tracking Protection marks a major new milestone in our battle against cross-site tracking: we now block fingerprinting scripts by default for all users, taking a new bold step in the fight for our users’ privacy.

  • Firefox replaces annoying notification request pop-ups with a more delightful experience, by default for all users. The pop-ups no longer interrupt your browsing, in its place, a speech bubble will appear in the address bar when you interact with the site.

  • Picture-in-picture video is now also available in Firefox for Mac and Linux: Select the blue icon from the right edge of a video to pop open a floating window so you can keep watching while working in other tabs or apps. Learn how the feature works.

Changed

  • Support for blocking images from individual domains has been removed from Firefox, because of low usage and poor user experience.

Enterprise

  • Experimental support for using client certificates from the OS certificate store can be enabled by setting the preference security.osclientcerts.autoload to true (Windows only).
