Released earlier this week on January 7th, the Mozilla Firefox 72 web browser is here to finally implement Picture-in-Picture (PiP) support for Linux-based operating systems, allowing users to watch videos from various websites in a floating, resizable window while working on other tabs or apps. Additionally, the Firefox 72 release further improves the Enhanced Tracking Protection feature by blocking fingerprinting scripts by default, replaces annoying notification request pop-ups with a speech bubble, and addresses a zero-day vulnerability with the Firefox 72.0.1 point release.
