Toggle Media Autoplay

[sblatz]

As a user, I want to be able to disable media autoplay on my browser, so I can save data and battery and have control over how I consume content.

UX mocks: https://app.abstract.com/share/cdba1651-670e-4412-8721-4d70ca025ffd?collectionLayerId=35603d5c-263c-4c70-b3fe-1ae23bd449c8&mode=design&sha=49143c0fafdf6c2d01f7c0b665c92a9fb7c0ebec

Acceptance Criteria

• I can use a toggle in settings to allow/block media autoplay
• When autoplay is disabled, audio and video content will not start playing unless I have initiated it.

Dependencies:

• GV already has an API for toggling autoplay: setAutoplayDefault.
  • A-C API for this is: allowAutoplayMedia.
• GV per-site autoplay controls which is also [Bug]Blocked media autoplay doesn't work properly  #5636
• Gecko dependency on play permission

GV bug to add a setting to either allow or block autoplay videos:
https://bugzilla.mozilla.org/show_bug.cgi?id=1522324

Gecko already has this functionality. Adding a GV setting should be very easy.

For TRIAGE: This should probably go into milestone 3 backlog, please size first though and indicate dependencies (planned currently for milestone 3 or 4)

As per comment, we might pull this back into a Battery saving story after MVP, however it should land for MVP as an individual feature.

@sblatz based on our conversation I am moving this issue to eng:qa:needed

[sblatz]

I believe we still need to remove the feature flag here, so I don't think QA will be able to verify just yet. Making this visible is on the top of my list :)

[vesta0]

Thanks for clarifying that @sblatz :)

[sblatz]

@vesta0 did you end up making a follow up ticket for these other features?

[vesta0]

Yes, here it is: #8017

QA can confirm that on the latest Nightly from 2/11, the Autoplay has 2 options:

• Video and audio blocked (Recommended) - set by default,
• Video and audio allowed.

Verified with Google Pixel (Android 10), and OnePlus (Android 9).
However, issue #5636 is still reproducible, so I'm only going to remove the qa:needed label.

I'm going to close this ticket and let's address #5636 as a follow up 😄
