In October 2025, Sebastian Boehmer developed the Privacy: Fireproof Visibility Setting feature for the duckduckgo/privacy-configuration repository. This addition enabled users to explicitly control the visibility of fireproof options within the privacy configuration interface, addressing a need for more granular user privacy controls. Sebastian approached the task using JavaScript, applying configuration management and front-end development skills to integrate the new setting seamlessly into the existing system. While the work focused on a single feature and did not involve bug fixes, it demonstrated a targeted and thoughtful enhancement to user privacy options, reflecting a focused contribution within a short project period.
