userScripts.resetWorldConfiguration()

Resets the configuration of a USER_SCRIPT world set by userScripts.configureWorld to the defaults specified in userScripts.WorldProperties. When the default world is reset, all worlds without an explicit configuration are also reset.

Changes to world configurations only apply to new instances of the world: A configuration won't apply to a world initialized by the execution of a user script in a document until the document is reloaded. However, the browser may revoke certain privileges when a configuration is updated. For example, message calls from a USER_SCRIPT world may fail when messaging is reset to false.

let resettingWorldConfiguration = browser.userScripts.resetWorldConfiguration(
  worldId       // optional string
);
