Web Vitals

Web Vitals are quality signals key to delivering great UX on the web (https://web.dev/vitals). This extension measures the Core Web Vitals, providing instant feedback on loading, interactivity and layout shift metrics. It is consistent with how these metrics are measured by Edge and reported to other Google tools (e.g. Edge User Experience Report, Page Speed Insights, Search Console).

The extension captures: Largest Contentful Paint Cumulative Layout Shift First Input Delay Interaction To Next Paint (experimental) First Contentful Paint Time To First Byte

The extension provides three core features:

1. Ambient Badge - This helps check if a page passing the Core Web Vitals thresholds.

Once installed, the extension will display a disabled state badge icon until you navigate to a URL. At this point it will update the badge to green or red depending on whether the URL passes the Core Web Vitals metrics thresholds.
