About this extension
Tracking Debugger records a chronological, evidence-focused view of Google tracking activity while you test a website in Firefox.

Use it to inspect:
  • Google Tag and Google Tag Manager resource loads
  • Data Layer events and Consent Mode commands
  • Direct GA4 event requests and detected website properties
  • GA4 key events and ecommerce parameter checks
  • Google Ads conversions, remarketing, call setup, and related requests
  • Configured server-side Google Tag Manager endpoints
  • Request status, redirects, decoded supported payloads, and request evidence
  • Protected user-data signals without retaining the protected values

Choose Direct browser tracking, Server-side tracking, or Both. Server-side modes require the custom endpoint domain so unrelated traffic is not incorrectly classified as sGTM.

Google Ads supporting requests are grouped into understandable activities. Potential repeated conversion executions are shown for review without claiming that a duplicate is confirmed. Evidence sequence links let you jump directly to the requests behind a finding.

Recordings remain in Firefox unless you explicitly export a JSON snapshot. The extension does not use telemetry, remote analytics, advertising, or AI uploads.
