pageAction.show()

Shows the page action for a given tab. The page action is shown whenever the given tab is the active tab.

show() overrides pattern matching, so the page action will be shown in the specified tab even if show_matches does not match the URL or hide_matches does.

Syntax

browser.pageAction.show(
  tabId // integer
)

Parameters

tabId
integer. The ID of the tab for which you want to show the page action.

Return value

A Promise that will be fulfilled with undefined.

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);
  }
});
