MDN’s new design is in Beta! A sneak peek: https://blog.mozilla.org/opendesign/mdns-new-design-beta/

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).

Each browsing context has a specific origin, the origin of the active document, and a history that lists all the displayed documents in order.

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