Firefox/Block autoplay in background
Overview
Background
he Block Playback feature is designed to block media with enabled autoplay if the tabs are opened in the background. Videos which autoplay in the background will now have their load deferred until the tab is visible for the first time this avoids autoplay during session restore and premature playback.Resources will still be preloaded but Firefox will delay the start of playback until the tab that contin a video with an enabled autoplay is visited. Once a tab / RenderFrame has ever played media before, it's allowed to continue to autoplay/autoload indefinitely; this is to support playlist type applications.The main advantages of the Block Playback feature is that it prevents obviously user annoyance but also conserves power as Firefox will only consume power once the tab is foregrounded
