In the Firefox 71 release for windows platforms, Mozilla introduced “picture-in-picture” features for web video, providing better support for sites such as YouTube, Netflix, Vimeo, and more. Now, Mozilla has added a Mute button to the picture-in-picture video in the nightly build version of Firefox 73. In the current Firefox stable and Nightly versions, the PiP window provides a tab that returns to the original, supports a pause/play, and a close button to exit PiP mode.

In contrast, Google Chrome offers similar picture-in-picture video controls, and even the “mute” and “skip ads” buttons, which have been removed.
The good news is that Mozilla Firefox is also introducing video mute for mini-play windows in the nightly build. Interested friends can refer to the following:
(1) Download the latest version of Firefox Nightly (Portal);
(2) Jump to about in the address bar: config tab;
(3) Search for ‘toggle’ and enable ‘media.videocontrols.photo-in-photo.audio-toggle.enabled’;
(4) Restart the browser.
Now you can play any video and tap the blue Picture In Icon when you visit video sites like YouTube.
In this mode, Firefox Nightly still offers the option to restore the video window, pause/play, mute, and turn off the video.
