looking for an experienced developer to build a custom browser (based on either Firefox or Chromium) that allows users to upload and apply full browser fingerprints from a JSON file. This browser will be used for anti-detect Browser purposes.

✅ Based on Firefox or Chromium (selectable or as per your expertise)

✅ UI or CLI to upload/import a JSON file containing full fingerprint data:

User-Agent

WebGL (vendor, renderer, image hash)

Canvas (dataURL, image hash)

AudioContext (waveform hash)

Fonts, screen size, language, timezone

WebRTC, MediaDevices, Battery, and more

✅ Automatically inject and spoof all values before page load

✅ Should support:

Iframes and nested contexts

OffscreenCanvas and OffscreenAudioContext

JavaScript traps like .toString() and Symbol

✅ Spoofed fingerprint should persist during session

✅ Logging system to verify spoofing is successful (e.g., compare before/after)

✅ (Optional) Proxy/VPN support (socks5, HTTP)
