[hhxiaohei]

Hardware

Pico VR G2

Steps to Reproduce

1.A vr web page

<audio id="music" src="1.mp3" autoplay="autoplay"></audio>

2.on Chrome,FF PC can autoplay,but in FirefoxReality audio is not work

FirefoxReality tell me:

 The play method is not allowed by the user agent or the platform in the current context, possibly because the user denied permission.

How can the audio autoplay by js or other? Thx!

@bluemarvin I believe you worked on adding API for autoplay settings to GV. Is this just a case of carrying them through to FxR?

• Block autoplay is unintentionally enabled in GeckoView mozilla-mobile/firefox-tv#2040

The settings dialog just needs the option added to it. GeckoView should already have the required API.

Based on UX design from Firefox, add setting in Security and Privacy pane, below the permissions settings, English text "Block websites from automatically playing sound", defaulting to enabled.

We'll need a separate issue to track allowing this on a per-site basis.

@thenadj - We're going to add this setting in since it's also in desktop and mobile. It'll use the same language and placement as we do there. No design needed, just FYI
