pageAction.show()

Shows the pageAction 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.

Note that calling show() has no effect on a tab with no content loaded.

Syntax

js
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.

Browser compatibility

BCD tables only load in the browser

Examples

This example shows the pageAction for the active tab when the user selects a context menu item.

Note: You'll need the contextMenus permission in your manifest to create context menu items.

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

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