1. Before version 56, the 'tabId' parameter was ignored, and the page action was shown for all tabs.

Examples

This example shows the page action for the active tab when the user selects a context menu item. Note that you'll need the contextMenus permission in your manifest to create context menu items.

browser.contextMenus.create({
  id: "show",
  title: "Show page action"
});

browser.contextMenus.onClicked.addListener(function(info, tab) {
  if (info.menuItemId == "show") {
    browser.pageAction.show(tab.id);
  }
});
