Spoof-when-possible browser personas, Tier-2 telemetry kill + artifact wipe, UI polish
Browser: identity persona dropdown (blend Windows-Chrome / Firefox / mac-Safari / hardened / custom) + cookie policy dropdown. Blend personas relax RFP/FPI/strict-TP so the machine looks normal while still hiding behind the chain. Persona TZ applied via env var; UA / language / locale / screen via user.js. WebRTC still forced off (it leaks real IP). Privacy: Telemetry kill toggle (DiagTrack, Activity History, ad ID, Cortana, scheduled tasks) with full snapshot/restore. One-button forensic artifact wipe (TEMP, Recent, Jump Lists, Prefetch, MRU, clipboard). UI: neon palette, glow card borders, gradient header banner. Co-authored-by: Cursor <cursoragent@cursor.com>

"""Browser identity personas + cookie policies.
|
||||
|
||||
The "lock everything down" approach (Firefox RFP + WebRTC off + cookies blocked)
|
||||
keeps you safe from fingerprinting but makes the machine *look weird* — sites
|
||||
flag you as suspicious and ban / captcha you. Worse: very few users use that
|
||||
config, so RFP-on is itself a fingerprint.
|
||||
|
||||
Two strategies are exposed:
|
||||
|
||||
• **Blend-in personas** — mimic the most common Windows-Chrome-US-en setup.
|
||||
JS / cookies / WebGL all work; everything looks normal; only WebRTC is
|
||||
blocked (because that leaks the real IP behind the proxy). The proxy
|
||||
chain itself does the actual hiding.
|
||||
|
||||
• **Hardened** — full RFP / blocked WebRTC / strict tracking / FPI. Stand-out
|
||||
but maximum block. Same behavior as the original profile.
|
||||
|
||||
Cookie modes are independent of persona and let the user pick per-session
|
||||
behavior from a dropdown.
