This is made to fight client-fingerprinting. This is not a browser extension, but a network app that aims to give you full control over your fingerprint.

Included:

- localhost mitmproxy addons - for JS injection and HTTPS header rewriting.

- JavaScript - Comprehensive JS proxies and property overrides. Fights font enumeration, navigator fingerprinting, webRTC leaks, and much much much more. Take a look to find out, or ask a question!

- Kernel level packet spoofing - eBPF program attached at traffic control hook allows for low-level packet header modification.
