Overview
Block Playback 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. This means no more "Where's that sound coming from?" moments when an ad for instance decides to autoplay in a tab you've specifically opened in the background. Resources will still be preloaded if indicated but Firefox will delay the start of playback until you actually visit the tab. 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. This feature prevents obviously user annoyance but also conserves power as Firefox will only consume power once the tab is foregrounded.
