pageAction.setTitle()

Sets the title of the page action. The title is displayed in a tooltip when the user hovers over the page action.

Syntax

js
browser.pageAction.setTitle(
  details // object
)

Parameters

details

object.

tabId

integer. The ID of the tab whose title you want to set.

title

string or null. The tooltip text.

If null is passed here, the title is reset to the title that was specified in the page_action manifest key.

Examples

Whenever a tab is updated, show the page action for that tab, and set its title to show the tab's ID:

js
browser.tabs.onUpdated.addListener((tabId, changeInfo, tabInfo) => {
  browser.pageAction.show(tabId);
  browser.pageAction.setTitle({
    tabId,
    title: `Tab ID: ${tabId}`,
  });
});
