When a browser is launched, it has a single BrowserContext used by default. The method [Browser.newPage](./puppeteer.browser.newpage.md) creates a page in the default browser context. Signature: ```typescript export declare class BrowserContext extends EventEmitter ``` Extends: [EventEmitter](./puppeteer.eventemitter.md) ## Remarks The Browser class extends from Puppeteer's [EventEmitter](./puppeteer.eventemitter.md) class and will emit various events which are documented in the [BrowserContextEmittedEvents](./puppeteer.browsercontextemittedevents.md) enum. If a page opens another page, e.g. with a `window.open` call, the popup will belong to the parent page's browser context. Puppeteer allows creation of "incognito" browser contexts with [Browser.createIncognitoBrowserContext](./puppeteer.browser.createincognitobrowsercontext.md) method. "Incognito" browser contexts don't write any browsing data to disk. The constructor for this class is marked as internal. Third-party code should not call the constructor directly or create subclasses that extend the `BrowserContext` class. ## Example ```js // Create a new incognito browser context const context = await browser.createIncognitoBrowserContext(); // Create a new page inside context. const page = await context.newPage(); // ... do stuff with page ... await page.goto('https://example.com'); // Dispose context once it's no longer needed. await context.close(); ``` ## Methods | Method | Modifiers | Description | | --- | --- | --- | | [browser()](./puppeteer.browsercontext.browser.md) | | The browser this browser context belongs to. | | [clearPermissionOverrides()](./puppeteer.browsercontext.clearpermissionoverrides.md) | | Clears all permission overrides for the browser context. | | [close()](./puppeteer.browsercontext.close.md) | | Closes the browser context. All the targets that belong to the browser context will be closed. | | [isIncognito()](./puppeteer.browsercontext.isincognito.md) | | Returns whether BrowserContext is incognito. The default browser context is the only non-incognito browser context. | | [newPage()](./puppeteer.browsercontext.newpage.md) | | Creates a new page in the browser context. | | [overridePermissions(origin, permissions)](./puppeteer.browsercontext.overridepermissions.md) | | | | [pages()](./puppeteer.browsercontext.pages.md) | | An array of all pages inside the browser context. | | [targets()](./puppeteer.browsercontext.targets.md) | | An array of all active targets inside the browser context. | | [waitForTarget(predicate, options)](./puppeteer.browsercontext.waitfortarget.md) | | This searches for a target in this specific browser context. |
