Session Copy for Firefox od itinfra7

Session Copy captures the cookies (including HttpOnly), localStorage, and sessionStorage of the active tab's site, encrypts them on your device with AES-256-GCM, and exports the result as a clipboard token or an encrypted .session file. Importing it in another browser opens the site with the session applied.

Features
- Copy / Paste an encrypted session through the clipboard
- Export / Import an encrypted .session file
- Login transfer mode (default): only authentication-related cookies and storage keys
- Container tabs and private windows: sessions are read from and restored into the active tab's own cookie store
- Clear site data: remove cookies, localStorage, and sessionStorage for the active site
- Light, dark, and system themes

Privacy
All processing happens locally. The add-on has no server, account, analytics, or network requests of its own, and runs no content scripts on the sites you visit.

A copied token or exported file is a bearer credential: anyone who has it can use the session until it expires or is revoked by the site.
