Browser | Playwright Python

A Browser is created via browser_type.launch(). An example of using a Browser to create a Page:

• Sync
• Async

from playwright.sync_api import sync_playwright, Playwright

def run(playwright: Playwright):
    firefox = playwright.firefox
    browser = firefox.launch()
    page = browser.new_page()
    page.goto("https://example.com")
    browser.close()

with sync_playwright() as playwright:
    run(playwright)

import asyncio
from playwright.async_api import async_playwright, Playwright

async def run(playwright: Playwright):
    firefox = playwright.firefox
    browser = await firefox.launch()
    page = await browser.new_page()
    await page.goto("https://example.com")
    await browser.close()

async def main():
    async with async_playwright() as playwright:
        await run(playwright)
asyncio.run(main())

In case this browser is obtained using browser_type.launch(), closes the browser and all of its pages (if any were opened).

In case this browser is connected to, clears all created contexts belonging to this browser and disconnects from the browser server.

The Browser object itself is considered to be disposed and cannot be used anymore.

Usage

browser.close()
browser.close(**kwargs)

Arguments

• reason str (optional) Added in: v1.40#

  The reason to be reported to the operations interrupted by the browser closure.

Returns

• NoneType#

note

CDP Sessions are only supported on Chromium-based browsers.

Returns the newly created browser session.

Usage

browser.new_browser_cdp_session()

Returns

• CDPSession#

Creates a new browser context. It won't share cookies/cache with other browser contexts.

note

If directly using this method to create BrowserContexts, it is best practice to explicitly close the returned context via browser_context.close() when your code is done with the BrowserContext, and before calling browser.close(). This will ensure the context is closed gracefully and any artifacts—like HARs and videos—are fully flushed and saved.

Usage

• Sync
• Async

browser = playwright.firefox.launch() 

context = browser.new_context()

page = context.new_page()
page.goto("https://example.com")


context.close()
browser.close()

browser = await playwright.firefox.launch() 

context = await browser.new_context()

page = await context.new_page()
await page.goto("https://example.com")


await context.close()
await browser.close()

Arguments

• accept_downloads bool (optional)#

  Whether to automatically download all the attachments. Defaults to true where all the downloads are accepted.

• base_url str (optional)#

  When using page.goto(), page.route(), page.wait_for_url(), page.expect_request(), or page.expect_response() it takes the base URL in consideration by using the URL() constructor for building the corresponding URL. Unset by default. Examples:

  • baseURL: http://localhost:3000 and navigating to /bar.html results in http://localhost:3000/bar.html
  • baseURL: http://localhost:3000/foo/ and navigating to ./bar.html results in http://localhost:3000/foo/bar.html
  • baseURL: http://localhost:3000/foo (without trailing slash) and navigating to ./bar.html results in http://localhost:3000/bar.html

• bypass_csp bool (optional)#

  Toggles bypassing page's Content-Security-Policy. Defaults to false.

• client_certificates List[Dict] (optional) Added in: 1.46#

  • origin str

    Exact origin that the certificate is valid for. Origin includes https protocol, a hostname and optionally a port.

  • certPath Union[str, pathlib.Path] (optional)

    Path to the file with the certificate in PEM format.

  • pfx bytes (optional)

    Direct value of the PFX or PKCS12 encoded private key and certificate chain.

  • passphrase str (optional)

    Passphrase for the private key (PEM or PFX).

  TLS Client Authentication allows the server to request a client certificate and verify it.

  Details

  An array of client certificates to be used. Each certificate object must have either both certPath and keyPath, a single pfxPath, or their corresponding direct value equivalents (cert and key, or pfx). Optionally, passphrase property should be provided if the certificate is encrypted. The origin property should be provided with an exact match to the request origin that the certificate is valid for.
