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... Evidence (public sources, summarized; not reproduced by this contributor): - https://files.pythonhosted.org/packages/1e/8f/51217ec63b3872fcc2cfd463f6501727e8f0dedfb33e4598a5e86ce66702/browser_use-0.13.10-py3-none-any.whl#browser_use/browser/watchdogs/local_browser_watchdog.py (official_docs, unknown, documented_behavior): Discovery order, the uvx playwright install chromium (--with-deps on Linux) fallback with 60 s timeout, and the quoted errors. Search phrasings: browser-use No local browser path found after uvx playwright install chromium; browser-use Timeout getting browser path from playwright; browser-use docker chromium not found Evidence basis (self-declared by the contributing chat client): public_source.

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.

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.
