Tab Group Switch is a Firefox add-on designed to enhance tab organization and management. This subscription-based tool allows users to save open tabs into customizable groups, making it easier to switch between them and manage resources effectively. Users can create new groups, add or replace tabs, and utilize the autosave feature for automatic session management. Additionally, it offers options for exporting and importing saved groups, providing flexibility and convenience for users who frequently work with multiple tabs.

The add-on provides a user-friendly interface with clear options for editing group names and managing tab statuses. However, it is important to note that switching groups will close and reload tabs, potentially resulting in the loss of form data and scrolling positions. While it effectively mimics some functionalities of the old Panorama tab groups, it currently has limitations with multiple windows and certain URL types. Overall, Tab Group Switch is a practical solution for users looking to streamline their tab organization in Firefox.
