In development since early December 2019, the Firefox 72 web browser promises to bring Picture-in-Picture (PiP) video controls for GNU/Linux and macOS platforms as Windows users already received PiP support in the Firefox 71 release. Picture-in-Picture is enabled by default, so after upgrading to Firefox 72, Linux and macOS users can finally watch videos from various websites in a floating window while working in other tabs by selecting the blue icon from the right edge of a video.
