Self-Destructing Cookies WebEx is a Firefox extension designed for web development and IT professionals. It provides enhanced cookie management by allowing users to choose between two operational modes: 'session' and 'tabs'. In 'session' mode, cookies are deleted when all browser windows are closed, ensuring that no traces are left after a session ends. In contrast, 'tabs' mode removes cookies related to a specific tab once it is closed, which is particularly useful for maintaining privacy when using multiple tabs of the same domain.

This extension is ideal for users who prioritize data security while browsing. It simplifies the cookie management process, making it easier to log in and out of various accounts without leaving unwanted cookies behind. However, it currently does not support cleaning localStorage, which may be a consideration for users who require comprehensive data management. Overall, Self-Destructing Cookies WebEx is a functional tool for those seeking to enhance their web development experience.
