claude-in-chrome doesn't recognise connected browsers after switching Claude accounts, even after logout and clearing the cache

Summary

On shared terminals where people switch between Claude accounts, claude-in-chrome stops
recognising the connected Chrome browsers once the account changes. It stays broken after
logging out of Claude Code, logging out of the Claude in Chrome extension, and clearing the
browser cache.

Environment

• OS: Windows 11 Enterprise (10.0.26200)
• Claude Code version: <!-- output of claude --version -->
• Claude in Chrome extension version: <!-- from chrome://extensions -->
• Chrome version: <!-- from chrome://version -->
• Number of Chrome browsers/profiles with the extension installed: <!-- e.g. 2 -->

Steps to reproduce

1. Sign in to Claude Code and the Claude in Chrome extension with Account A.
2. Run /chrome and confirm the browser tools work.
3. Log out of Claude Code (/logout) and log out of the extension.
4. Clear the browser cache.
5. Sign in to Claude Code and the extension with Account B.
6. Run /chrome or call any claude-in-chrome tool.

Expected

The browsers signed in with Account B are listed and can be selected.

Actual

The browsers are not recognised.
Please reconnect the Claude Chrome extension.
