Hello all, we have video player inside iframe. <iframe src="https://x.com/example/player" allow="autoplay '*' ; fullscreen '*'"></iframe> in Firefox 70, it will successfuly make an autoplay of video content, in mute condition. But in Firefox 71, it will make a non-autoplay of video content. we check the video unmute and video mute conditions with can-autoplay library. How to make Firefox 71 works just like Firefox 70 ???
