Either fully removes navigator.bluetooth or replaces it with a fixed, non-revealing response set, to prevent fingerprinting/tracking via Bluetooth adapter presence and paired devices
Userscript that prevents sites from probing whether you have a Bluetooth adapter or querying previously-paired devices via navigator.bluetooth.
It either removes the API completely (block mode) or keeps it present but always reports no adapter, no paired devices, and rejects device-selection requests without ever showing you a native picker (fixed mode) so nothing real ever leaks.
