The getAllCookieStores() method of the cookies API returns a list of all cookie stores.

This is an asynchronous function that returns a Promise.


let gettingStores = browser.cookies.getAllCookieStores()



Return value

A Promise that will be fulfilled with an array of cookies.CookieStore objects representing all the existing cookie stores.

Browser compatibility

BCD tables only load in the browser


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.

function logStores(cookieStores) {
  for (const store of cookieStores) {
    console.log(`Cookie store: ${}\n Tab IDs: ${store.tabIds}`);


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

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