About this extension
ZeroX is a high-performance Firefox extension engineered for security professionals, penetration testers, and web developers who require precision proxy control and streamlined auditing workflows.

Designed to bridge Firefox's Multi-Account Containers directly with Burp Suite and external proxies, ZeroX empowers you to isolate test scopes, identify traffic origins in real time, and bypass client-side header restrictions without leaving your browser.

  • ⚡ Smart Burp Proxy Management
  • Route all browser traffic or selectively isolate specific Container tabs through Burp Suite.
  • Instant port presets (8080, 8081, 8888) with quick inline address editing.
  • Zero-latency, in-memory request interception.
  • 🏷 Container Color Header Injection (X-ZeroX-Color)
  • Automatically injects X-ZeroX-Color: <color> into HTTP request headers for isolated container tabs.
  • Effortlessly filter and track multi-user sessions inside Burp Suite Logger, Repeater, and Intruder.
  • 🛡 Security Header Stripping
  • Dynamically remove restrictive response headers (CSP, X-Frame-Options, X-XSS-Protection, HSTS) during security assessments.
  • 🎨 8 One-Click Chromatic Container Launchers
  • Instantly spawn isolated container sessions (Red, Orange, Yellow, Green, Cyan, Blue, Purple, Pink) with a single click.
  • 🔍 DevTools Message Panel
  • Integrated developer tools panel for deep postMessage inspection, filtering, and cross-origin frame analysis.
  • 🔒 Privacy & Zero Telemetry
  • 100% local execution with zero tracking, zero external font downloads, and zero third-party telemetry.

  • Web Application Penetration Testers & Bug Bounty Hunters.
  • Security Engineers auditing multi-tenant access control & session isolation.
  • Full-stack developers testing OAuth, CORS, and cross-origin communication.
