SessionDeck for Firefox per Samuel Caetité

SessionDeck lets you run multiple isolated sessions of the same website side by side in Firefox.

Create separate sessions for personal, work, client, or other accounts. Each session uses its own Firefox Container, keeping cookies and login state isolated while letting you reopen the session whenever you need it.

With SessionDeck you can:

• Create named sessions for any website
• Open multiple isolated accounts in the same Firefox window
• Reopen sessions using their existing login state
• Rename and manage saved sessions
• Recover sessions if SessionDeck's local metadata is lost
• Delete sessions and their containers when no longer needed

SessionDeck is built directly on Firefox's native Containers capability. It does not read or transmit your passwords, authentication tokens, or cookie values.

Everything stays local in Firefox. There is no SessionDeck account, backend, cloud sync, analytics, telemetry, or tracking.

SessionDeck is site-agnostic and does not attempt to bypass website restrictions or security mechanisms.
