# BrowserContext class
[BrowserContext](./puppeteer.browsercontext.md) represents individual sessions within a [browser](./puppeteer.browser.md).
When a [browser](./puppeteer.browser.md) is launched, it has a single [browser context](./puppeteer.browsercontext.md) by default. Others can be created using [Browser.createIncognitoBrowserContext()](./puppeteer.browser.createincognitobrowsercontext.md).
[BrowserContext](./puppeteer.browsercontext.md) [emits](./puppeteer.eventemitter.md) various events which are documented in the [BrowserContextEvent](./puppeteer.browsercontextevent.md) enum.
If a [page](./puppeteer.page.md) opens another [page](./puppeteer.page.md), e.g. using `window.open`, the popup will belong to the parent [page's browser context](./puppeteer.page.browsercontext.md).
#### Signature:
```typescript
export declare abstract class BrowserContext extends EventEmitter<BrowserContextEvents>
```
**Extends:** [EventEmitter](./puppeteer.eventemitter.md)&lt;[BrowserContextEvents](./puppeteer.browsercontextevents.md)&gt;
## Remarks
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
Creating an incognito [browser context](./puppeteer.browsercontext.md):
```ts
// 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();
```
