MDN wants to talk to developers like you:

This API is available on Firefox OS for internal applications only.


The set method allows to change a given permission for a given app.

Depending on the privileges of the applications, some permissions are implicit. If for some reason the application tries to change permission for an implicit one, an error will be thrown. In order to avoid such errors, it's possible to check if the permission is explicit with the PermissionSettings.isExplicit() method.


 var value = navigator.mozPermissionsettings.set(permission, value, manifest, origin, browserFlag)


A string with the name of the permission to retrieve.
A string representing the new value for the permission, one of deny, prompt, or allow.
A string representing the URL of the manifest of the app to check, or for an app running inside the browser, the URL of the browser app manifest.
A string representing the domain name of the app.
A boolean indicating if the app is running in the browser instead of as an installed app.


Not part of any specification.
