Within days after releasing Firefox 71 with Picture in Picture video on Windows, Mozilla has started adding more features to PiP. The browser feature which works on all video sites including YouTube, Netflix, Vimeo etc, has got the Mute button or Audio toggle in Firefox 73 which is on Nightly. The new button can be enabled and you can use it to mute the playing video in Picture in Picture mode in the Firefox browser.
As of now, In the stable and Nightly versions of Firefox, PiP window displays controls to go back to the origin tab, pause/play video and close button to exit PIP mode. Google Chrome also offers the same buttons for Picture-in-Picture, although the browser once supported Mute and Skip Ad buttons, it’s no longer the case right now.
