Bug Description

On Ubuntu Server (headless environment), the browser tool can 'open' pages successfully, but 'snapshot' and 'screenshot' operations fail with an error about Chrome extension relay.

Environment

• OpenClaw Version: 2026.2.12
• OS: Ubuntu Server 24.04 (Linux 6.8.0-100-generic)
• Browser: Playwright Chromium 1208
• Node.js: v22.22.0
• Running Mode: Headless (noSandbox: true)

Error Message

Steps to Reproduce

1. Start browser:
2. Open page:
3. Try snapshot: → Fails

Expected Behavior

Snapshot should return the page content/dom structure.

Actual Behavior

Snapshot fails with Chrome extension relay error, even though using 'openclaw' profile (Playwright native mode).

Troubleshooting Attempted

• ✅ Restarted Gateway
• ✅ Updated OpenClaw to latest (2026.2.12)
• ✅ Installed Playwright system dependencies (libgbm1, libnss3, etc.)
• ✅ Set environment variable
• ❌ Issue persists

Analysis

The error message "Chrome extension relay is running" suggests the code may be incorrectly entering extension relay mode, even when using 'profile=openclaw' which should use Playwright native mode.

Configuration

Additional Context

• Browser process starts successfully (PID visible)
• Page opens successfully (targetId returned)
• Only snapshot/screenshot operations fail
• Running on Ubuntu Server without GUI (headless environment)
