Affecting Permissions.query()’s userVisible option has been renamed to userVisibleOnly

Published: | Categories: DOM

Description

The userVisible option for the Permissions.query and revoke methods, implemented with Firefox 46 and 47 respectively, has been renamed to userVisibleOnly as per the latest Push API spec.

Firefox actually throws a NS_ERROR_NOT_IMPLEMENTED exception when userVisibleOnly is set to true, because Firefox relies on its own quota system instead of this option, unlike Google Chrome. One demo app is broken with this change. There’s a plan to remove the support for PushPermissionDescriptor itself from Firefox so that the option will just be ignored rather than throwing.

Update: The PushPermissionDescriptor dictionary has been removed for the compatibility with Google Chrome requiring the userVisibleOnly option, so that it is now simply ignored in Firefox.
