cookies.CookieStore

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

id

A string representing the unique identifier for the cookie store.

incognito Optional

A boolean value that indicates whether this is an incognito cookie store. This property is not supported in Chrome or Safari. However, you can identify incognito cookie stores in Chrome because their id is always "1".

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

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