Highlights (selects) one or more tabs. Tabs are specified using a window ID and a range of tab indices.

This is an asynchronous function that returns a Promise.


let highlighting = browser.tabs.highlight(
  highlightInfo         // object




windowId Optional

integer. ID of the window that contains the tabs.

populate Optional

boolean. Defaults to true. If set to false, the windows.Window object won't have a tabs property containing a list of tabs.Tab objects representing the tabs open in the window.

Note: Populating the window (the default behavior) can be an expensive operation if there are lots of tabs. For better performance it's recommended to manually set populate to false if you don't need tab details.


array of integer values specifying one or more tab indices to highlight. Previously highlighted tabs not included in tabs will stop being highlighted. The first tab in tabs will become active.

Return value

A Promise that will be fulfilled with a windows.Window object containing details about the window whose tabs were highlighted. If the window could not be found or some other error occurs, the promise will be rejected with an error message.
