Raise these on Raspberry Pi, low-end VPS, or older hardware where Chromium
starts slowly. Values must be positive integers up to `120000` ms; invalid
config values are rejected.
- Repeated managed Chrome launch/readiness failures are circuit-broken per
profile. After several consecutive failures, OpenClaw pauses new launch
attempts briefly instead of spawning Chromium on every browser tool call. Fix
the startup problem, disable the browser if it is not needed, or restart the
Gateway after repair.
- `actionTimeoutMs` is the default budget for browser `act` requests when the caller does not pass `timeoutMs`. The client transport adds a small slack window so long waits can finish instead of timing out at the HTTP boundary.
- `tabCleanup` is best-effort cleanup for tabs opened by primary-agent browser sessions. Subagent, cron, and ACP lifecycle cleanup still closes their explicit tracked tabs at session end; primary sessions keep active tabs reusable, then close idle or excess tracked tabs in the background.
