+# Multi-page scenarios
+
+Playwright can automate scenarios that span multiple browser contexts or multiple
+tabs in a browser window.

+
+## Multiple contexts
+
+[Browser contexts](core-concepts.md#browser-contexts) are isolated environments
+on a single browser instance. Playwright can create multiple browser contexts
+within a single scenario. This is useful when you want to test for
+multi-user functionality, like chat.
+
+```js
+const { chromium } = require('playwright');
+
+// Create a Chromium browser instance
+const browser = await chromium.launch();
+
+// Create two isolated browser contexts
+const userContext = await browser.newContext();
+const adminContext = await browser.newContext();
+
+// Load user and admin cookies
+await userContext.addCookies(userCookies);
+await adminContext.addCookies(adminCookies);
+```
+
+#### API reference
+
+- [class `BrowserContext`](./api.md#class-browsercontext)
+- [`browser.newContext([options])`](./api.md#browsernewcontextoptions)
+- [`browserContext.addCookies(cookies)`](api.md#browsercontextaddcookiescookies)
+
+## Multiple pages
+
+Each browser context can host multiple pages (tabs).
+
+* Each page behaves like a focused, active page. Bringing the page to front
+  is not required.
+* Pages inside a context respect context-level emulation, like viewport sizes,
+  custom network routes or browser locale.
+
+```js
+// Create two pages
+const pageOne = await context.newPage();
+const pageTwo = await context.newPage();
+
+// Get pages of a brower context
+const allPages = context.pages();
+```
+
+#### API reference
+
+- [class `Page`](./api.md#class-page)
+- [`browserContext.newPage()`](./api.md#browsercontextnewpage)
+- [`browserContext.pages()`](./api.md#browsercontextpages)
+
+## Handling new pages
+
+The `page` event on browser contexts can be used to get new pages that are
+created in the context. This can be used to handle new pages opened by
+`target="_blank"` links.
+
+```js
+// Get page after a specific action (e.g. clicking a link)
+const [newPage] = await Promise.all([
+  context.waitForEvent('page'),
+  page.evaluate(() => window.open('https://google.com', '_blank'))
+])
+await newPage.waitForLoadState();
+console.log(await newPage.title());
+
+// Get all new pages (including popups) in the context
+context.on('page', async page => {
+  await page.waitForLoadState();
+  await page.title();
+})
+```
+
+#### API reference
+
+- [event: 'page'](./api.md#event-page)
+
+## Handling popups
+
+If the page opens a pop-up, you can get a reference to it by listening to the
+`popup` event on the page.
+
+This event is emitted in addition to the `browserContext.on('page')` event, but
+only for popups relevant to this page.
+
+```js
+// Get popup after a specific action (e.g., click)
+const [popup] = await Promise.all([
+  page.waitForEvent('popup'),
+  page.click('#open')
+]);
+await popup.waitForLoadState();
+await popup.title();
+
+// Get all popups when they open
+page.on('popup', async popup => {
+  await popup.waitForLoadState();
+  await popup.title();
+})
+```
