First decide whether you need to stop a slow browser operation or close a browser that has been idle. Those are different timers. For Playwright MCP, use --idle-timeout=<milliseconds> to control when an idle server-launched browser closes. Playwright library timeouts and Selenium waits instead bound particular operations; they do not automatically shut down an idle browser.
Choose the timeout that matches the problem
“Inactivity timeout” can mean either an operation has taken too long or a browser has received no work for a while. The first is an operation timeout: it can stop a navigation, script, or element search. The second is a lifecycle timeout: it closes or disconnects an otherwise idle browser or session.
Before changing a setting, identify the resource you want to protect and the event that should end its timer. If a page sometimes takes longer to load, tune its navigation limit. If an automation server should release a browser after its controller stops making tool calls, configure an idle lifecycle timeout where that server supports one. Do not substitute one for the other.
- Operation runs too long: set the timeout for that operation or its relevant category.
- Element is not present yet: use an element-wait strategy suited to the framework.
- Browser should close after no work: use an explicit lifecycle control, if available, or end the session deliberately.
Set an idle timeout in Playwright MCP
Playwright MCP documents a server-level --idle-timeout option. Its unit is milliseconds. The documented default is one hour without tool calls for a headless browser launched by the server. Set a different duration by passing the desired number of milliseconds:

--idle-timeout=900000This example sets the idle interval to 900,000 milliseconds (15 minutes). Choose a duration based on how long a legitimate pause between tool calls can be and how much browser capacity you want to keep reserved; there is no universal best value.
Disable automatic closure
Use 0 to disable automatic idle closure:
--idle-timeout=0That setting removes this automatic cleanup safeguard. Use it only when another part of your system owns browser cleanup, or when indefinite reuse is intentional.
Understand which browser modes are affected
By default, headed browsers and browsers attached through --cdp-endpoint or --extension are not automatically closed. The Playwright MCP guide says an explicit idle timeout can be applied to any mode. If you are relying on the default, account for the browser mode rather than assuming every browser has the same lifecycle.
The timer is based on the absence of tool calls, not on whether a page is visually changing or whether a browser process looks busy. Confirm the option is supplied to the MCP server process that owns the browser, not merely to code running inside a page.

Playwright library timeouts are operation limits
Playwright’s Page API has method-level timeout options and default-timeout setters on a page or browser context. It also documents navigation-specific timeout setters. These limit operations; they are not browser idle teardown controls.
Set the scope deliberately
Use a method-level timeout when one operation is exceptional and should have its own bound. Use a page or context default when a consistent limit should apply to relevant operations in that scope. Use a navigation-specific default when navigations need a different budget from other actions.
Many listed Page operations have no timeout by default (0), while some wait methods have their own defaults. A value of timeout: 0 disables the relevant operation timeout. Do not assume a single default applies to every Playwright call: check the particular method and the version you use.
// JavaScript: bound one navigation operation (milliseconds)
await page.goto('https://example.com', { timeout: 30000 });When an operation timeout expires, treat the result as a failed or interrupted operation and handle it in your automation flow. Do not expect the browser to close just because a page action reached its limit. If the real requirement is to release an idle browser, configure the owning server or close the browser/session explicitly.

Set Selenium timeouts by operation type
Selenium documents separate controls for script execution, page loading, and implicit element lookup. For a new WebDriver session, its Browser Options documentation gives defaults of 30,000 ms for scripts, 300,000 ms for page loads, and 0 ms for implicit element lookup. These are operation defaults, not a universal idle-session shutdown duration.
| Timeout | What it bounds | Documented new-session default |
|---|---|---|
| Script | Execution of scripts through the WebDriver timeout control | 30,000 ms |
| Page load | Waiting for a page load to complete | 300,000 ms |
| Implicit wait | Element-location calls across the session | 0 ms |
These defaults are stated in Selenium’s Browser Options documentation inspected in 2026. They are not recommendations for every application. Set limits according to the operations and load conditions your own automation must handle.
Example: set Selenium timeouts in Python
from selenium import webdriver
driver = webdriver.Chrome()
driver.set_script_timeout(30) # seconds
driver.set_page_load_timeout(120) # seconds
driver.implicitly_wait(0) # seconds
try:
driver.get("https://example.com")
finally:
driver.quit()Python WebDriver timeout methods take seconds, unlike the millisecond values in Selenium’s documented defaults. The example uses a 30-second script limit, a 120-second page-load limit, and no implicit wait; adjust them for the work you run. Keep the cleanup in a finally block so an exception does not bypass deliberate session termination.
Implicit and explicit waits
An implicit wait applies globally to element-location calls. Selenium’s waiting-strategies guide warns: “Do not mix implicit and explicit waits.” Combining them can produce unpredictable timing. If you need condition-based waits, prefer an explicit wait strategy and keep the implicit wait at zero rather than layering two waiting systems.

- Please Note: To reach 10Gbps speed, keep the cable under 3.3 ft. For USB A Male to USB C adapters, try flipping the USB C connector. USB C Male to USB A adapters support bidirectional 10Gbps transfer within 3.3 ft
Neither an implicit nor an explicit element wait means “close the browser if no automation command arrives.” Once work is finished, end the WebDriver session with quit; Selenium’s driver-session guide recommends it to stop the session.
Puppeteer: a wait timeout is not idle cleanup
Puppeteer’s Page API search result documents a 30-second default for the wait timeout and says it can be changed with Page.setDefaultTimeout. That is a wait-operation setting, not evidence that Puppeteer automatically closes an idle browser after that interval. Consult the API for the specific wait you use, and close the browser deliberately when your automation lifecycle is complete.
Plan timers, recovery, and cleanup
Choose a value from observed work, not a cross-framework rule
Timeout numbers are meaningful only with their scope and unit. A 30-second script limit, a 30-second element wait, and a 30-second idle lifecycle limit would each expire under different conditions. Estimate normal and worst-case operation durations in your environment, then give important work enough time while ensuring failed work does not occupy resources indefinitely.
Handle expiry as a normal failure path
- Log which operation or lifecycle timer expired, along with the page or task being processed.
- For an operation timeout, decide whether to retry, capture diagnostic state, or fail the task. Retrying blindly can repeat side effects.
- For an idle browser closure, expect the next task to need a new browser or session rather than assuming the old page is still usable.
- Use explicit cleanup paths, such as Selenium
quit, even when an idle timeout is configured.
Balance reliability and resource use
Shorter operation limits fail slow but valid work sooner; longer limits can leave a stuck job occupying capacity for longer. Shorter idle lifecycle limits release unused browsers sooner but may require a fresh startup after a long pause. Account for startup cost, concurrency, task duration, and whether a controller can resume work. A timeout is a bound, not a substitute for health checks, retry policy, or cleanup.

Troubleshooting timeout behavior
- The browser stays open after setting an action timeout: that timeout only bounds the action. Configure a lifecycle timeout in the browser-owning service, or close the session explicitly.
- Playwright MCP closes the browser sooner or later than expected: verify that
--idle-timeoutis passed to the active server, that the value is in milliseconds, and that it is not0. Check whether the browser was launched headless, headed, or attached through CDP or the extension. - A wait never seems to expire: check whether the particular Playwright operation defaults to no timeout, whether a method-level setting overrides a default, and whether
0disabled that operation’s limit. - Selenium element searches take longer than expected: inspect the session-wide implicit wait and any explicit waits. Avoid mixing implicit and explicit waits.
- Selenium reports a page-load or script timeout: identify which of those distinct limits fired and tune that category, rather than changing the element wait without evidence.
- The WebDriver process remains after a failure: make sure session cleanup runs in a
finallypath and callsquit. - Behavior differs across framework versions: verify the exact method and defaults in the documentation for the framework version in use. The values above are documented defaults, not a guarantee that every version or wrapper behaves identically.

Frequently Asked Questions
Does an operation timeout automatically kill the browser?
Not in the documented Playwright Page, Selenium wait, or Puppeteer Page timeout controls described here. Use an explicit lifecycle setting or session cleanup.
Are the Selenium defaults a recommendation for every test suite?
No. They are documented defaults for a new session, not universal target values. Set timeouts to suit the operation and environment.
