cookies.CookieStore

The CookieStore type of the cookies API represents a cookie store in the browser.

Windows in different browsing modes may use different cookie stores — a private browsing/incognito mode window, for instance, will use a separate cookie store from a non-incognito/private window.

Values of this type are objects, which can contain the following properties:

id

A string representing the unique identifier for the cookie store.

incognito

A boolean value that indicates whether this is an incognito cookie store.

tabIds

An array of integers, which identifies all of the browser tabs that share this cookie store.

In the following snippet, the cookies.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(store of cookieStores) {
    console.log(`Cookie store: ${store.id}\n Tab IDs: ${store.tabIds}`);
  }
}

let getting = browser.cookies.getAllCookieStores();
getting.then(logStores);

The following code snippet gets all cookie stores and then logs the total number of stores and how many of those stores are incognito.

browser.cookies.getAllCookieStores().then((stores) => {
  let incognitoStores = stores.map(store => store.incognito);
  console.log(`Of ${stores.length} cookie stores, ${incognitoStores.length} are incognito.`);
});
