If you’re using Firefox as a default web browser and fan of the Media Control feature, then there’s good news for you. Firefox Nightly now supports Media Control Feature. That means, just like the Chrome and Edge browser, you can also enjoy Media Controls in the Firefox browser too.
When you play video in the Firefox browser and press the volume or multimedia key (Play/Pause/Stop) instantly Media control dialog will appear from where you can manage media playback. Like you can control volume, play next or previous track. Apart from this, it also gives information about the media file and video thumbnail.
