## BrowserContext class
BrowserContexts provide a way to operate multiple independent browser sessions. 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.
<b>Signature:</b>
```typescript
export declare class BrowserContext extends EventEmitter
```
<b>Extends:</b> [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

| [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. |

| [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. |
