Firefox 72.0, See All New Features, Updates and Fixes:

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.
