Save Tabs - Browser Session Manager is a Firefox extension designed for efficient tab management. This subscription-based tool allows users to save all tabs from the current window, other windows, or all open windows for later restoration. It frees up memory by enabling users to close saved tabs while retaining their state. The extension employs the built-in sync API, facilitating seamless storage and restoration across multiple devices. Additionally, it offers password protection for stored tabs, utilizing SHA-256 encryption to ensure data security.

The extension's features include saving and restoring window dimensions, incognito states, pinned states, and tab groupings. Users can manage their sessions with ease, and the functionality allows for editing sessions directly from the popup view. Notably, stored sessions can be restored with specific key combinations, enhancing user experience. However, it's important to note that lost passwords for protected tabs cannot be recovered.
