What issue are you seeing?

Environment

• macOS
• Codex Desktop App: 26.506.31421
• Chrome: 147.0.7727.139
• Codex Chrome Extension: 1.1.4
• Chrome extension ID: hehggadaopoacecdllhhajmbjkdcmajg

Problem

The Codex Chrome plugin channel consistently times out. Reinstalling the Chrome plugin and reinstalling/restarting Codex did not fix it.

The Chrome extension and native host appear to be installed correctly, and the low-level socket responds, but Codex's official browser runtime initialization hangs.

What I tried

• Reinstalled the Codex Chrome plugin from Codex plugin UI
• Reinstalled/restarted Codex Desktop App
• Restarted Chrome
• Opened Chrome with the Default profile
• Restarted the Chrome extension host process
• Verified native host manifest
• Verified extension is installed and enabled

Diagnostics

check-extension-installed.js --json reports:

• installed: true
• registered: true
• enabled: true
• version: 1.1.4_0

check-native-host-manifest.js --json reports:

• exists: true
• nameMatches: true
• hasExpectedOrigin: true
• correct: true

Low-level socket calls succeed:

• getInfo returns Chrome extension info:
• name: Chrome
• version: 1.1.4
• type: extension
• getUserTabs returns Chrome tabs successfully.

But this official initialization path still times out:

const { setupAtlasRuntime } = await import('/Users/a1010/.codex/plugins/cache/openai-bundled/chrome/0.1.7/scripts/browser-client.mjs');
await setupAtlasRuntime({ globals: globalThis });
