Changelog since 1.0.7
Security signal → triggering script

Capture call stack and caller script URL/line/col on first JS-hook hit
Fetch capped script source into a background ScriptCache
Inspector Triggering script block with View script and Analyze with AI
Investigation report includes script meta and source preview
Canvas fingerprinting (evidence-based)

Group related Canvas API calls into one Canvas activity (not one alert per API)
Record call arguments, canvas size/type, create path, and draw→read chains
Light data-flow hints (hash/encode/network after canvas reads)
Classification: Confirmed / Likely / Possible / Ordinary / Unknown with evidence score
Supporting evidence, missing evidence, and network correlation (or explicit “unavailable / not observed”)
Investigation report sections for interpretation, alternatives, and next steps
WebGL fingerprinting (evidence-based)

Group WebGL queries into one WebGL activity; lone getContext("webgl") is not treated as fingerprinting
Capture method args (e.g. getParameter(UNMASKED_RENDERER_WEBGL)) and return-value previews (with redaction/hash for sensitive strings)
Stages: API Access → Capability Detection → GPU Identification → Collection → Processing → Transmission
Per-axis confidence: WebGL usage, GPU detection, fingerprint collection, transmission (NOT OBSERVED when unproven)
Data-flow and network correlation; inspector and report show accessed APIs, returned values, supporting/missing evidence, and behavior notes without claiming intent.

Added update check mechanism through AMO API.

1.0.6 — Broader fingerprint and probe alerts beyond Canvas and WebGL: Audio, WebRTC, media devices, WebGPU, Client Hints, fonts, screen/hardware harvest, geolocation, permissions, speech voices, CSS/feature probing, DNS leak and TLS/QUIC collectors, plus local-network port scans.

Version 1.0.5

NetScope now alerts when a site fingerprints your browser - Canvas and WebGL fingerprinting

Version 1.0.1

Added real-time port scan detection: the extension now monitors requests to local network addresses (127.0.0.1, localhost, 192.168.x.x, 10.x.x.x) and detects scanning patterns
Added browser push notifications when a port scan is detected (source, port, scan count)
Added in-panel alert overlay showing port scan details with auto-dismiss
Added "notifications" permission to support system-level alerts
