MDN wants to learn about developers like you:

A browsing context is the environment in which a browser displays a Document (normally a tab nowadays, but possibly also a window or a frame within a page).

Communication between browsing contexts is severely restricted. Between browsing context of the same origin, a BroadcastChannel can be opened and used.
