About Bullshield - User-Agent & Fingerprint Spoofer

Bullshield is a Chromium-first browser extension focused on coherent user-agent and browser fingerprint spoofing. Instead of changing only one visible value, Bullshield aligns related browser surfaces so websites receive one consistent generated profile instead of conflicting signals. Bullshield is designed to go beyond simple user-agent switching. It works to keep multiple browser identity surfaces aligned so fingerprinting and detection pages see a coherent generated profile instead of obvious mismatches. Core capabilities: - user-agent spoofing - Client Hints spoofing - coherent fingerprint profile generation - browser identity alignment - locale and timezone alignment - WebGL-related fingerprint masking - per-site control - manual profile generation - optional timed profile refresh - onboarding and advanced settings Bullshield is designed to operate locally inside the browser extension runtime.
