[DOCS] Edge support contradicts between Claude Code Chrome docs and Help Center article (Edge works with Claude Code)

### Documentation Type

Incorrect/outdated documentation

### Documentation Location

https://code.claude.com/docs/en/chrome and https://support.claude.com/en/articles/12012173-get-started-with-claude-in-chrome

### Section/Topic

Browser support (Microsoft Edge / other Chromium browsers) — Claude Code "Use Claude Code with Chrome" Prerequisites note vs. Help Center "Install Claude in Chrome" note

### Current Documentation

Two official pages make opposite claims about the same extension.

Claude Code docs, https://code.claude.com/docs/en/chrome (Prerequisites note):
> "Chrome integration works with Google Chrome and Microsoft Edge. Claude Code also detects the extension and sets up the connection in other Chromium-based browsers, including Brave, Arc, Vivaldi, and Opera."

Help Center, https://support.claude.com/en/articles/12012173-get-started-with-claude-in-chrome (Install section):
> "Note: Claude in Chrome is not supported on other Chromium-based web browsers or mobile devices."

### What's Wrong or Missing?

The two pages contradict each other. The Help Center note is wrong for Claude Code users and is the page a new user reads first, so it steers Edge users away from a feature that works.

Verified 2026-08-30 on Windows 11 with the extension installed in Microsoft Edge from the Chrome Web Store: /chrome reports Status: Enabled / Extension: Installed, and Claude Code's browser tools navigate tabs, read page text, and take screenshots in Edge.

Two smaller gaps on the same pages:

1. The Help Center's pinning step says "clicking the puzzle piece icon". Edge's Extensions button is a different icon, so the instruction does not match what an Edge user sees.

2. After a fresh install the extension did not connect to Claude Code until its side panel had been opened once. Until then /chrome showed Enabled / Installed but "Select browser…" listed nothing and browser tools returned "Browser extension is not connected", with the native messaging host registration in place. Opening the panel fixed it with no restart. Troubleshooting does not mention this step.

### Suggested Improvement

1. Help Center, "Install Claude in Chrome": remove "Claude in Chrome is not supported on other Chromium-based web browsers", or scope it to the side-panel product and add: "For Claude Code and Cowork, the extension also works in Microsoft Edge and other Chromium-based browsers — see Use Claude Code with Chrome."

2. Help Center, pinning step: replace "clicking the puzzle piece icon" with "clicking the Extensions button in the toolbar" so it holds for Edge and other Chromium browsers.

3. Claude Code docs, Troubleshooting → "Extension not detected": add "Open the extension's side panel once after installing; it does not initialize its Claude Code connection until it has been opened."

### Impact

High - Prevents users from using a feature

### Additional Context

Environment: Windows 11 Pro 10.0.26200, Microsoft Edge, Claude in Chrome extension 1.0.85, Claude Code 2.1.251 (native), Max plan.

One note for the Windows Troubleshooting section: launching the native host by hand while a Claude Code session is running logs "listen EADDRINUSE" on the bridge pipe. That is expected — the running session already owns the pipe — and was not the cause of the connection failure above. The current text presents EADDRINUSE as a conflict to fix by restarting.

Screenshots available on request.

Start by comparing the Claude Code Chrome page and the Help Center article at the two URLs, including the Prerequisites, Install, and Troubleshooting sections. Confirm the Edge and other Chromium-browser wording, the Extensions-button terminology, and the side-panel initialization behavior; done means the contradictory guidance and connection troubleshooting are consistent for Claude Code users.
