Left unmanaged, browsers become a primary vector for data exfiltration, shadow IT via rogue extensions, and unauthorized telemetry collection. System administrators require a deterministic, programmable method to enforce security baselines. For cross-platform Endpoint management, Mozilla provides a native policy engine driven by a single configuration file:  policies.json . This approach replaces legacy, brittle JavaScript-based AutoConfig setups ( mozilla.cfg ), offering a standardized, OS-agnostic method to lock down preferences, deploy internal extensions, and strictly disable telemetry Firefox instances might otherwise broadcast.
