contextualIdentities.get()

Gets information about a contextual identity, given its cookie store ID.

This is an asynchronous function that returns a Promise.

Syntax

var getContext = browser.contextualIdentities.get(
  cookieStoreId                  // string
)

Parameters

cookieStoreId

string. The ID of this contextual identity's cookie store. Because contextual identities each have their own cookie store, this serves as an identifier for the contextual identity itself.

Return value

A Promise that will be fulfilled with a ContextualIdentity that describes the identity. If the identity could not be found or the contextual identities feature is not enabled, the promise is rejected.
