The Mozilla Permissions API makes it easier for users to determine the accessibility of APIs. The API allows developers to build applications that provide consistent options for querying the statuses of APIs. This makes it possible users to query the granting or denial of permissions to access APIs. The API’s support for desktop browsers is currently restricted to Chrome and Firefox (Gecko), while the mobile browsers it supports include Android Webview, Firefox Mobile (Gecko), and Chrome for Android. This API is currently experimental.
