Allows developers and power users to modify HTTP requests and responses (headers, redirects, cancellations) for debugging, CORS testing, anti-hotlinking bypass, ad blocking, and API testing without needing backend changes

User creates rules via the options page or popup panel, defining URL match patterns and actions (modify headers, redirect, cancel). Rules are stored locally in chrome.storage and applied automatically via declarativeNetRequest API or webRequest API when matching requests are made.

Target users: Web developers / Front-end engineers / QA testers / Power users who need to modify browser requests

Source code is webpack-bundled/minified making exact line-level tracing difficult
The 'Lite' variant implies a full 'Header Editor' version exists with potentially more features, but no upgrade path was found in this extension's code
Cloud backup feature has documentation links to he.firefoxcn.net but actual cloud service integration code was not fully traced

Monetization

No paid features detected

The extension is explicitly described as '100% FREE, no ADs'. The 'pro' keyword matches are all from third-party libraries (classnames, RE2JS, Semi Design UI) and locale files with 'pro' as part of variable names or UI strings, not paid feature indicators. 'license' matches are MIT license headers. No payment platforms (Stripe, PayPal, etc.), subscription APIs, or upgrade/paywall UI were detected. The 'Lite' name and 'lite_not_support' locale strings indicate this is a feature-limited variant compared to the full 'Header Editor' extension, but no paid upgrade path exists within this extension itself.

Confidence: 90
Payment platform: --
Source: AI / High
Login required: No
Reason: The extension operates entirely locally using chrome.storage for data persistence. No login flows, authentication endpoints, or user account systems were found in the source code. The 'token', 'auth', 'session', and 'jwt' keyword hits are all in third-party library code (webpack metadata, CSS tokens, session rules API), not user authentication. The store description explicitly states 'no data collection'.
