Environment
- OS: Windows 11 Home Single Language (10.0.26200)
- Browser: Google Chrome
- Claude Code: latest via CLI
Steps taken
- Extension icon visible and pinned in toolbar, but clicking it does nothing (no popup, no error).
- Confirmed via Claude Code MCP connection check: browser extension not connected.
- Fully uninstalled and reinstalled the extension from the Chrome Web Store - issue persisted.
- Force-killed all Chrome processes and relaunched Chrome fully - issue persisted.
- Checked chrome://extensions - no red "Errors" button shown, extension appears enabled, no disable_reasons in Preferences/Secure Preferences.
- Confirmed the extension (ID fcoeoabgfenejglbffodgkkbkcdhcgfn) is correctly registered as enabled in the Chrome profile Secure Preferences file, not disabled by policy or blocklist.
- Temporarily disabled a third-party extension (McAfee WebAdvisor) that was also installed in the same profile - issue persisted.
Expected behavior
Clicking the extension icon should open the popup and allow connecting to Claude Code.
Actual behavior
Extension icon is present and enabled, but clicking it produces no popup, no visible error, and the Claude Code MCP connection reports the extension as not connected.
