Autoplay on Web
On the web, browsers typically restrict the autoplay behavior of web pages. For more details, see the following links:
Autoplay on Extension Pages
However, there is no documentation or specification indicating whether this behavior is equally effective on extension pages.
The goal of this issue is to clearly define its behavior in the (Web or Browser Extensions) specification and implementation.
Some Situations:
HTMLMediaElement.play()
Some Use Cases:
AUDIO_PLAYBACK
reason in the offscreen document.Currently, browsers seem to exempt extensions from this restriction in most cases. If so browsers need to clarify this behavior. But if we have concerns about this behavior, perhaps we can consider adding a new
autoplay
permission in the future (that will cause breaking change), like thenotifications
permission, or some other ways. Whether it should be looser or stricter, it's an undefined place at the moment. Of course, from a developer's perspective, since there is no sensitive data involved, and there are web store policy requirements, it would be better to be lenient.PS: I open this issue because there is a discussion about it today.
