Containers

Keeps sites in separate compartments so their cookies and logins cannot see each other.

How containers work

A container is an isolated slice of storage. A site opened in one cannot read the cookies or logins of the same site in another, so you can be signed into several accounts at once without them colliding.

Right-click a link or tab to open or reopen it in a container. A workspace can be tied to one, so everything opened inside it is compartmented automatically.

Private containers

Open in Private Container makes a throwaway compartment: it behaves like a container while it is open and takes its storage with it when it closes. Useful for one-off logins you do not want kept.
