menus.refresh()
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 amenus.onShown event handler, after the handler has made any updates to the menu.
Firefox makes this function available via thecontextMenus namespace as well as themenus namespace.
This is an asynchronous function that returns aPromise.

function updateMenuItem(linkHostname) { browser.menus.update(openLabelledId, { title: `Open (${linkHostname})`, }); browser.menus.refresh();}browser.menus.onShown.addListener((info) => { if (!info.linkUrl) { return; } let linkElement = document.createElement("a"); linkElement.href = info.linkUrl; updateMenuItem(linkElement.hostname);});
