Compatibility notes


  • Always returns the same default cookie store with ID 0. All cookies belong to this store.


In the following snippet, the getAllCookieStores() method is used to retrieve all the cookie stores currently available in the browser, and print out each cookie store ID, and the tabs that currently share each cookie store.

chrome.cookies.getAllCookieStores(function(cookieStores) {
  for(var i = 0; i < cookieStores.length; i++) {
    console.log('Cookie store: ' + cookieStores[i].id +
                '\n Tab IDs: ' + cookieStores[i].tabIds);

Each member of the cookieStores array is a cookies.CookieStore object.


This API is based on Chromium's chrome.cookies API. This documentation is derived from cookies.json in the Chromium code.
