SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Test browser extensions in real-browser environments to observe live behavior and DevTools state when issues only appear in real use, not in simulated tests.

Core Features & Use Cases

Real-browser verification workflow and debugging heuristics for Chrome, Edge, Chromium, Brave, and Firefox.
Build artifact validation with fresh profiles and unpacked extensions to reproduce user reports accurately.
Guided workflow for testing content scripts, popups, options pages, hover/focus bugs, and browser-specific regressions.

Quick Start

Run a minimal local repro in a fresh browser instance using the unpacked extension from your build and capture DevTools targets.

FAQPage Schema

How do I reproduce a browser extension bug in a real browser environment?▼

To reproduce an extension bug, load your unpacked build artifact into a fresh browser profile and use a minimal local repro page. This workflow verifies live DOM state and DevTools targets for accurate bug reproduction across Chrome, Edge, Brave, and Firefox.

Why does my extension work in automated tests but fail in a real browser?▼

Extensions often fail in real browsers due to environment-specific regressions not present in simulated tests. Real-browser verification diagnoses these issues by testing unpacked installs with fresh profiles to observe live behavior, hover and focus bugs, and actual DevTools targets.

Can I test unpacked extensions across different Chromium browsers?▼

Yes, you can test unpacked extensions across Chrome, Edge, Chromium, and Brave. The workflow supports cross-browser verification by loading built artifacts into fresh profiles of each browser to identify browser-specific regressions in content scripts and UI behavior.

What's the best way to debug content scripts and popups during extension testing?▼

The best way to debug content scripts and popups is using a guided real-browser workflow with DevTools. Load the unpacked extension in a fresh profile, open a minimal local repro page, and inspect live DOM state and DevTools targets to anchor your findings.

Do I need a fresh browser profile to validate extension behavior?▼

Yes, a fresh browser profile is required to accurately reproduce user reports and validate build artifacts. It isolates the unpacked extension from existing state, ensuring observed content script behavior and popup issues reflect the extension rather than profile configuration.

Does real-browser testing work for Firefox extensions?▼

Real-browser testing supports Firefox alongside Chrome, Edge, Chromium, and Brave. It applies the same verification workflow using unpacked installs and minimal local repro pages to capture live DOM state and diagnose browser-specific regressions in Firefox.
