Sidebery 4 features
Session Manager 5 features
  • Efficient Tab Management
    Sidebery allows users to manage tabs and containers in a vertical sidebar, making navigation and organization more intuitive and efficient, especially for users who have many tabs open simultaneously.
  • Customizable Interface
    The addon offers extensive customization options for the sidebar, including themes, styles, and layout adjustments, enabling users to tailor the interface to their personal preferences.
  • Resource Management
    By using Firefox's container tabs, Sidebery helps in better resource management and organization, allowing users to separate different types of web activities and reduce memory consumption.
  • Keyboard Shortcuts
    Contains support for various keyboard shortcuts, making tab manipulation faster and enhancing the overall user experience for power users who prefer using the keyboard over the mouse.

Possible disadvantages

  • Learning Curve
    The extensive features and options available in Sidebery might present a learning curve to new users, making it initially overwhelming for those not familiar with advanced tab management.
  • Firefox Specific
    Sidebery is only available on Firefox, limiting its use for individuals who are on other browsers and creating dependency on a single browser ecosystem.
  • Potential Performance Impact
    Having numerous tabs and containers managed through Sidebery might impact browser performance, especially on systems with limited resources, as it requires additional memory and processing power.
  • Complexity for Casual Users
    For users who do not require advanced tab management, the additional features and complexity might seem unnecessary and could complicate their browsing experience.
  • Session Restoration
    Session Manager allows users to restore their previous browsing sessions, saving all open tabs and windows, which is especially useful after a browser crash or accidental closure.
  • Session Organization
    The tool provides an organized view of all saved sessions, making it easy for users to manage and switch between different sets of tabs and windows.
  • Automated Backups
    Session Manager can automatically save and back up sessions at regular intervals, ensuring that recent browsing activities are not lost.
  • Customization Options
    Users can customize session saves by choosing which windows and tabs to include, providing flexibility in how sessions are managed.
  • User-friendly Interface
    The tool features an intuitive and user-friendly interface, making it accessible to both novice and experienced users.

Possible disadvantages

  • Compatibility Issues
    Being an extension for older versions of Firefox, Session Manager may not be compatible with the latest browser updates, limiting its usage.
  • Performance Impact
    Running this extension can lead to increased memory usage and longer startup times for the browser, particularly if numerous sessions are saved.
  • Security Concerns
    Storing session data may pose security risks, especially if sensitive information is left in open tabs and not adequately protected.
  • Limited Support
    With the development community moving on to newer platforms, the support and updates for Session Manager might be limited, affecting its reliability.
  • Complexity for New Users
    While the interface is generally user-friendly, some new users might find the range of options and settings overwhelming initially.

Overall verdict

  • Session Manager was a well-regarded Firefox extension that reliably saved and restored browsing sessions, tabs, and windows, offering robust crash recovery beyond the browser's built-in features.

  • Provides strong crash recovery to prevent loss of open tabs
  • Allows manual saving of named sessions for later retrieval
  • Offers granular control over session and window restoration
  • Was highly rated and trusted by power users during its active period

Recommended for

  • Users running legacy Firefox versions (pre-Quantum/XUL-based)
  • Power users who manage many tabs and windows simultaneously
  • People who need reliable crash recovery and session backups
  • Researchers or professionals who want to save and reload named browsing sessions
