Modern Kiosk is a free Firefox add-on that provides kiosk functionality for public browsing. Designed to limit user access to the operating system, it allows users to navigate a specified URL in full-screen mode. Installation is straightforward, and users can quickly set their desired kiosk URL, activating the kiosk mode via the context menu or tab icon. The current version offers essential features suitable for controlled browsing environments, making it an effective tool for libraries, schools, and other public spaces.

The add-on is under active development, with planned updates set to enhance its capabilities. Upcoming features include domain whitelisting to restrict browsing to specific websites, the ability to close all other windows except the active kiosk window, and options for an exit key combination or password for additional security. These improvements will significantly strengthen Modern Kiosk as a reliable solution for managing public web access.
