Allows web developers and power users to quickly identify which HTTP protocol version a website is using without opening DevTools or using external tools.

User navigates to any website → content script reads nextHopProtocol from Navigation Timing API → background script receives the protocol string → sets appropriate icon and tooltip in the toolbar. User can click icon to open chrome://net-export.

Target users: Web developers / Network engineers / Power users interested in web performance and protocol support

Extension is very small (124-byte content script, 3.5KB background script) — straightforward to analyze with high confidence.
Icon/binary files are not textually analyzed but are only referenced by the background script for display purposes.

Monetization

No paid features detected

No billing, subscription, payment, license, or upgrade logic exists in the source code. The 'pro' keyword matches are false positives from minified code where 'pro' appears as a substring of other words (e.g., 'performance'). The extension is a simple open-source tool with no gated features.

Confidence: 99
Payment platform: --
Source: AI / High
Login required: No
Reason: The extension has no login UI, no account system, no authentication flow, and no external service requiring credentials. The content script reads browser Navigation Timing 2 API data locally and sends it to the background script — no network requests to authenticated endpoints.
