SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill lets users automate browser tasks in their real Chrome session without repeatedly signing in or manually navigating pages.

Core Features & Use Cases

  • Authenticated browser control: Operate the user's existing Chrome tabs and reuse real cookies and login sessions through the Ethan Browser extension.
  • Web interaction: Create or attach to sessions, inspect pages, click controls, fill forms, press keys, switch tabs, extract content, execute JavaScript, and capture screenshots.
  • Reliable automation: Use structured page references, CSS or XPath selectors, snapshot pagination, controlled retries, and agent-browser fallback when the extension is unavailable.
  • Use Case: Complete a form on a website where the user is already logged in, verify the result, and leave the relevant tab available for the user to review.

Quick Start

Ask the browser skill to attach to the current Chrome tab and complete the requested webpage interaction using the user's existing login session.

Frequently Asked Questions about use-browser

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I automate web scraping on pages that require my existing login session?▼

By attaching to your existing Chrome tabs through the Ethan Browser extension, browser automation reuses your real cookies to perform web scraping and interaction without manual re-authentication.

Can I fill out forms and click controls on a website I am already logged into?▼

Yes, browser automation supports clicking controls, filling forms, pressing keys, and switching tabs directly on your authenticated Chrome pages using structured page references and CSS or XPath selectors.

Do I need a specific browser extension to control my real Chrome tabs?▼

Authenticated browser control requires the Ethan Browser extension for real-cookie access, though an agent-browser fallback handles common connection failures when the extension is unavailable.

What is the best way to extract content and capture screenshots from local browser tabs?▼

Automating interactions with real Chrome tabs supports content extraction, JavaScript evaluation, and screenshot capture using controlled retries and snapshot pagination for reliable page inspection.

Why does my browser automation fail when selecting elements on dynamic web pages?▼

Dynamic page automation failures are mitigated by using selector fallbacks between CSS and XPath, controlled retry limits, and structured page references to ensure reliable web interaction.

How do I run JavaScript code on a live web page in my local browser?▼

Attaching browser automation to your real Chrome tab enables direct page inspection and JavaScript evaluation within your authenticated session without manual navigation.
