Couldn't list connected browsers: JSON Parse error: Unexpected identifier "Browser"

Steps to Reproduce

The browser extension is still not connected. The error from the /chrome command (JSON Parse error: ... "Browser")
confirms the bridge can't reach a running extension.

Let's get it connected. Please work through these in order:

1. Confirm the extension is installed — open chrome://extensions in Chrome and look for the Claude extension. If it's

not there, install it from https://claude.ai/chrome.

1. Confirm it's enabled — make sure its toggle is on (not greyed out), and that you're not in an Incognito window

where it's disabled.

1. Log into claude.ai in Chrome with the same account as Claude Code — chaseprogression@gmail.com. A mismatched

account is the most common cause.

1. Fully restart Chrome — quit completely (Cmd+Q, not just close the window) and reopen. First-time installs usually

don't register until a full restart.

After that, type /chrome again (or just tell me) and I'll re-check the connection.
