Chrome extension not connecting on Windows (v2.1.32)

Description

After updating Claude Code to v2.1.32, the Claude in Chrome extension no longer connects. The MCP server reports as reconnected via /mcp, but all browser automation tool calls (e.g., tabs_context_mcp) return "Browser extension is not connected."

This was previously working in Brave browser before the update.

Environment

• Claude Code version: 2.1.32
• Extension version: 1.0.45
• OS: Windows 11
• Browsers tested: Chrome (primary), Brave (previously worked)

Steps to Reproduce

1. Update Claude Code to v2.1.32
2. Install Claude in Chrome extension (v1.0.45) in Google Chrome
3. Log into claude.ai in Chrome
4. Create a "Claude" tab group in Chrome
5. Run /mcp in Claude Code — shows "Reconnected to claude-in-chrome"
6. Attempt any browser automation tool call (e.g., tabs_context_mcp)
7. Returns "Browser extension is not connected"

What I've Verified

All of these check out correctly:

• Registry: HKCU\Software\Google\Chrome\NativeMessagingHosts\com.anthropic.claude_code_browser_extension exists and points to correct manifest
• Manifest JSON: C:\Users\chris\AppData\Roaming\Claude Code\ChromeNativeHost\com.anthropic.claude_code_browser_extension.json exists with correct extension ID
• Batch file: C:\Users\chris\.claude\chrome\chrome-native-host.bat exists and points to correct Node/CLI paths
• Extension ID: fcoeoabgfenejglbffodgkkbkcdhcgfn matches in both manifest allowed_origins and installed extension
• Claude Code version: 2.1.32 (above 2.0.73 minimum)
• Extension version: 1.0.45 (above 1.0.36 minimum)

Troubleshooting Attempted

• Restarted Chrome and Brave multiple times
• Uninstalled and reinstalled the extension
• Set Chrome as default browser
• Ran /chrome → "Reconnect extension" multiple times
• Ran /mcp to reconnect the MCP server multiple times
• Verified logged into claude.ai with same account as Claude Code

Additional Context

• The extension was working in Brave prior to the v2.1.32 update
• The /chrome "Reconnect extension" option initially opened tabs in Brave (default browser) instead of Chrome. After switching default browser to Chrome, it opened correctly in Chrome but still didn't resolve the connection issue.
• The superpowers skill also broke after the same update (had to disable it), suggesting possible broader issues with the 2.1.32 release on Windows.
