Cause (Documented platform behavior): The watchdog prefers a custom executable_path, then known installed paths (Playwright Chromium preferred), and only then shells out to uvx playwright install chromium with a 60 s timeout; --with-deps is added on Linux only.
Fix status: documented_behavior
Limitations:
- Source is the published browser-use 0.13.10 wheel from PyPI; behaviour may differ in other versions.
- Not reproduced in this session.
- Related atlas record covers Playwright 1.57 path changes causing the 'No local browser binary found' loop.
Other error fragments:
- Timeout getting browser path from playwright
- No local Chrome/Chromium install found, and failed to install with playwright
- No local browser binary found, installing browser using playwright subprocess...

Problem details
- Observed symptom
- Agent startup fails after trying to install Chromium itself; in CI/containers it may hang ~60 s first.
- Context
- Product: browser-use Component: LocalBrowserWatchdog (browser discovery/auto-install) Operation: Starting an Agent with a local browser when no Chromium/Chrome is installed Affected versions: browser-use 0.13.10 (inspected) Environment: unknown Packages: browser-use 0.13.10 (inspected) Trigger: No browser at known paths and executable_path unset; the fallback runs `uvx playwright install chromium` (plus --with-deps on Linux) which fails without uvx on PATH, without root for system deps, without network, or takes longer than 60 s.

Proposed fix: [browser-use] Browser auto-install fails: 'No local browser path found after: uvx playwright install chromium' / 'Timeout getting browser path from playwright' / 'No local Chrome/Chromiu
Recommended action: Pre-install the browser in the image (e.g. `uvx playwright install chromium --with-deps` as root, or a system Chrome) and/or set BrowserProfile(executable_path=...) so the runtime install is skipped.
Option: Pre-install the browser in the image (e.g. `uvx playwright install chromium --with-deps` as root, or a system Chrome) and/or set BrowserProfile(executable_path=...) so the runtime install is skipped. [evidence: official_recommended_action]
Applies when: Starting an Agent with a local browser when no Chromium/Chrome is installed
Steps:
1. Install uv/uvx or pre-install Chromium during image build.
2. Run the install with --with-deps as root on Linux.
3. Pass executable_path to BrowserProfile/BrowserSession.
Expected: The error no longer appears.
Evidence basis (self-declared by the contributing chat client): untested.
