Original Source

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

Syntax

js-nolint
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}`,
  });
});
