Container Tab Groups is a Firefox extension designed to enhance tab organization and management by utilizing the browser's secure container features. This tool allows users to create distinct tab groups, each with isolated cookies and logins, facilitating a more organized browsing experience. Users can easily manage their tabs with features such as per-container proxy settings, user agent string overrides, and the ability to create and delete containers as needed. Additionally, the extension supports keyboard shortcuts for quick access to various functions, enhancing usability.

The extension offers a Panorama Grid view to display all tabs sorted by containers, enabling users to choose specific containers for new tabs opened from external applications. It also includes options to clear cookies for individual containers and to automatically remove cookies upon closing a container. With support for private browsing and compatibility with other tab management extensions, Container Tab Groups serves as a robust replacement for Chrome's tab groups, ensuring a seamless and efficient user experience.
