> ## Agent Instructions
> Anchor Browser provides cloud browsers for AI agents and automation: stealth browsing with residential proxies, managed authentication into third-party web apps, and browser sessions that run reliably at scale. AI agents that need Anchor credentials should start with https://docs.anchorbrowser.io/quickstart/agent-access. This flow lets agents obtain an API key programmatically without creating a dashboard account. Read that page before attempting authentication or API access.

# Popup Blocker

> Block cookie banners and consent dialogs in your browser sessions

Popup blocking is enabled by default in Anchor Browser. It blocks cookie banners and consent dialogs to create cleaner automation experiences.

<Note>
  Popup blocking is enabled by default. Disable it only if you need to test popup-related functionality.
</Note>

## Quick Start

<CodeGroup>
  ```javascript node.js theme={null}
  import { client, Sessions } from 'anchorbrowser';

  (async () => {
    client.setConfig({ auth: () => process.env.ANCHOR_API_KEY });
    
    const session = await Sessions.createSession({
      body: {
        // Optional: Enabled by default (both), so this configuration is not required
        browser: {
          adblock: {
            active: true  // Required for popup blocking
          },
          popup_blocker: {
            active: true  // Blocks cookie banners and consent dialogs
          }
        }
      }
    });
    
    console.log("Session:", session.data.id);
  })().catch(console.error);
  ```

  ```python python theme={null}
  import os
  from anchorbrowser import Anchorbrowser

  anchor_client = Anchorbrowser(api_key=os.getenv("ANCHOR_API_KEY"))

  session = anchor_client.sessions.create_session(
      # Optional: Enabled by default (both), so this configuration is not required
      browser={
          "adblock": {
              "active": True  # Required for popup blocking
          },
          "popup_blocker": {
              "active": True  # Blocks cookie banners and consent dialogs
          }
      }
  )

  print("Session:", session.data.id)
  ```
</CodeGroup>

<Warning>
  Popup blocking requires ad blocking to be active. Disabling ad blocking will result an error.
</Warning>

## Disabling Popup Blocker

To disable popup blocking for a session, set `active: false` in the popup\_blocker configuration:

<CodeGroup>
  ```javascript node.js theme={null}
  import { client, Sessions } from 'anchorbrowser';

  (async () => {
    client.setConfig({ auth: () => process.env.ANCHOR_API_KEY });
    
    const session = await Sessions.createSession({
      body: {
        browser: {
          // Optional: ad blocking is enabled by default, so this configuration is not required
          adblock: {
            active: true  // Ad blocking must remain active
          },
          // Required to disable popup_blocker
          popup_blocker: {
            active: false  // Disables popup blocking for this session
          }
        }
      }
    });
    
    console.log("Session:", session.data.id);
  })().catch(console.error);
  ```

  ```python python theme={null}
  import os
  from anchorbrowser import Anchorbrowser

  anchor_client = Anchorbrowser(api_key=os.getenv("ANCHOR_API_KEY"))

  session = anchor_client.sessions.create_session(
      browser={
          # Optional: ad blocking is enabled by default, so this configuration is not required
          "adblock": {
              "active": True  # Ad blocking must remain active
          },
          # Required to disable popup_blocker
          "popup_blocker": {
              "active": False  # Disables popup blocking for this session
          }
      }
  )

  print("Session:", session.data.id)
  ```
</CodeGroup>
