Session Boss is a Firefox extension designed for effective session management, allowing users to capture and restore browser windows and tabs seamlessly. It features automated saving of browsing sessions with scheduled backups and URL change detection, ensuring that users can manage their browsing activities without losing data. The extension also supports saving and restoring tab containers, providing flexibility in how sessions are organized and accessed.

Key functionalities include grouping sessions, searching, filtering, and the ability to undo or redo changes. Users can export and import sessions in JSON format, making it easy to backup and transfer session data. Notably, Session Boss prioritizes user privacy by excluding private browsing windows from automatic backups, while also offering options for manual inclusion through user preferences.
