What This Extension Does

Live Resource Override intercepts and replaces web resource responses (JavaScript, CSS, XHR/fetch) with user-defined modifications for debugging purposes. It also supports header modification, API response mocking, and script/style injection.

Data Collection

This extension does not collect, transmit, or share any data with any third party. Specifically:

  • No analytics or tracking of any kind
  • No telemetry data
  • No user behavior monitoring
  • No data sent to external servers
  • No cookies set by the extension

Data Storage

All user-defined override rules are stored locally in your browser using the chrome.storage.local API. This data never leaves your device. You can export your rules as a JSON file and delete all data by uninstalling the extension.

Permissions

The extension requests the following permissions, all required for core functionality:

  • storage + unlimitedStorage — Store user-defined override rules locally
  • declarativeNetRequest — Intercept, redirect, and block matching network requests
  • declarativeNetRequestWithHostAccess — Modify request and response headers
  • declarativeNetRequestFeedback — Show matched rule counts for debugging
  • tabs — Read current tab URL to display relevant rules in the popup
  • host_permissions: <all_urls> — Required to intercept requests on any domain the user targets

Third-Party Services

This extension does not use any third-party services, APIs, or SDKs.

Website Analytics

This website (not the extension) uses Google Analytics 4 to understand visitor traffic and improve the documentation. The extension itself contains zero tracking code.
