Resolved 💬 3 comments Opened Mar 8, 2026 by tnguyenppdata Closed Mar 11, 2026
Environment:
- OS: Windows 11 Pro
- Claude Code version: (check with
claude --versionin terminal) - Chrome version: (from chrome://version)
- Extension ID: fcoeoabgfenejglbffodgkkbkcdhcgfn
## What happened:
The Claude browser extension is installed and active in Chrome, but Claude Code
cannot connect to it. The error message returned is:
"Browser extension is not connected. Please ensure the Claude browser extension
is installed and running (https://claude.ai/chrome), and that you are logged into
claude.ai with the same account as Claude Code."
## Steps taken:
- Installed extension from https://claude.ai/chrome
- Logged into claude.ai with the same account used for Claude Code
- Confirmed accounts match in extension settings
- Disabled and re-enabled the extension
- Fully restarted Chrome
- Kept claude.ai tab open and active
- Set site access to "On all sites"
## Expected behavior:
Claude Code should detect and connect to the browser extension.
## Actual behavior:
Connection always fails with the above error message. No "Claude Code" or
"Desktop" connection option is visible in the extension sidebar.
