  description

  Timing Side-Channel Profiler (TSP) is a developer and security testing tool that helps identify performance and timing anomalies in web applications.
  
  With TSP, you can:
  
  Monitor fetch() and XMLHttpRequest timings.
  
  Observe resource loading metrics (DNS, connect, redirect, response).
  
  Track paint events (first paint, first contentful paint).
  
  Run controlled active probes (opt-in) to compare response times across endpoints.
  
  Export results for offline analysis (e.g., JSON → Jupyter notebook).
  
  This extension is designed for developers, researchers, and bug bounty hunters who need visibility into possible timing-based vulnerabilities or performance bottlenecks.
  
  ⚠️ Note: This tool does not collect personal data or transmit logs externally. All captured data stays local to the user’s browser.
