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, the promise is fulfilled with null.
