Features & Capabilities

Session Boss is a powerful Chrome extension designed to save and restore your browser tab sessions seamlessly. It automatically captures window and tab states, supports scheduled and on-change backups, and allows restoring individual windows or tabs. The extension also supports tab containers, session grouping, searching, undo/redo functionality, and lazy loading of tabs to optimize performance. Its robust export and import features enable offline backups and easy session transfers.

Prioritizing user privacy, Session Boss excludes private browsing windows from saved sessions by default to prevent accidental data leaks. It operates fully offline without collecting or sending user data. With detailed session management and automatic backup scheduling, Session Boss ensures your browsing sessions are safe, easily recoverable, and organized for productivity enhancement.

User Reviews

Session Boss is praised for effectively saving and restoring browser sessions, often preferred over default managers and supporting Tree Style Tabs. However, multiple users report critical issues like sudden loss of saved sessions and slow performance, especially with large tab counts. The extension lacks key features expected in modern session managers and suffers from an outdated UI and occasional bugs in settings. Users recommend regular manual backups as a precaution, and while its core functionality is valued, instability and missing functionalities limit its reliability.

Pros

Effectively saves and restores tabs and sessions, often considered a lifesaver by users.
Better alternative to some other session managers like Session Buddy and recommended over Mozilla's default option.
Supports automatic saving of sessions when changes occur, avoiding unnecessary backups.
Offers support for Tree Style Tabs and maintains container tab information.
Enables exporting and importing sessions between devices for recovery purposes.

Cons

Unreliable session saving, with multiple users reporting sudden loss or deletion of all saved sessions.
Performance issues, including slow restoration of large sessions and increased CPU usage causing sluggish browsing.
Lack of essential features like multi-tab selection, merging sessions, duplicate tab management, and robust import/export options.
User interface is outdated, not intuitive, and visually unappealing to many users.
Settings/preferences sometimes do not work properly, such as ignored backup limits and lack of synchronization across devices.

Is Session Boss Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Session Boss requires a few sensitive permissions. Exercise caution before installing.

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.
