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
)
highlightInfo
object.
windowId {{optional_inline}}
integer. ID of the window that contains the tabs.populate {{optional_inline}}
: boolean. Defaults to true. If set to false, the {{WebExtAPIRef('windows.Window')}} object won't have a tabs property containing a list of {{WebExtAPIRef('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
populatetofalseif you don't need tab details.
tabs
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.A Promise that will be fulfilled with a {{WebExtAPIRef('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.
