Permissions

Up until Firefox OS 1.4, The Camera API was a certified API, so not accessible to third party apps. From Firefox OS 2.0 onwards, the permission level has been downgraded to privileged, so it is now available for developers to use in their apps.

"permissions": {
  "camera": {
    "description": "Required for accessing cameras on the device."
  }
