Refreshes a menu that's being shown.

Updates the extension's menu items in the menu that the browser is currently showing, including changes that have been made since the menu was shown. Has no effect if the menu is not being shown. Rebuilding a shown menu is an expensive operation, only invoke this method when necessary.

This would typically be called from inside a menus.onShown event handler, after the handler has made any updates to the menu.

Firefox makes this function available via the contextMenus namespace as well as the menus namespace.

This is an asynchronous function that returns a Promise.





Return value

A Promise that is fulfilled with no arguments.

This example listens for the context menu to be shown over a link, then updates the openLabelledId menu item with the link's hostname:

function updateMenuItem(linkHostname) {
  browser.menus.update(openLabelledId, {
    title: `Open (${linkHostname})`

browser.menus.onShown.addListener(info => {
  if (!info.linkUrl) {
  let linkElement = document.createElement("a");
  linkElement.href = info.linkUrl;
