 - **Anti-bot Bypass**: Advanced stealth capabilities with `StealthyFetcher` and fingerprint spoofing. Can easily bypass all types of Cloudflare's Turnstile/Interstitial with automation.
 - **Session Management**: Persistent session support with `FetcherSession`, `StealthySession`, and `DynamicSession` classes for cookie and state management across requests.
 - **Proxy Rotation**: Built-in `ProxyRotator` with cyclic or custom rotation strategies across all session types, plus per-request proxy overrides.
-- **Domain Blocking**: Block requests to specific domains (and their subdomains) in browser-based fetchers.
+- **Domain & Ad Blocking**: Block requests to specific domains (and their subdomains) or enable built-in ad blocking (~3,500 known ad/tracker domains) in browser-based fetchers.
+- **DNS Leak Prevention**: Optional DNS-over-HTTPS support to route DNS queries through Cloudflare's DoH, preventing DNS leaks when using proxies.
 - **Async Support**: Complete async support across all fetchers and dedicated async session classes.

 1. The `disable_resources` option made requests ~25% faster in tests for some websites and can help save proxy usage, but be careful with it, as it can cause some websites to never finish loading.

+### Pre-Navigation Setup
+If you need to set up event listeners, routes, or scripts that must be registered before the page navigates, use `page_setup`. This function receives the `page` object and runs before `page.goto()` is called.
+
+```python
+from playwright.sync_api import Page
+
+def capture_websockets(page: Page):
+    page.on("websocket", lambda ws: print(f"WebSocket opened: {ws.url}"))
+
+page = DynamicFetcher.fetch('https://example.com', page_setup=capture_websockets)
+```
+Async version:
+```python
+from playwright.async_api import Page
+
+async def capture_websockets(page: Page):
+    page.on("websocket", lambda ws: print(f"WebSocket opened: {ws.url}"))
+
+page = await DynamicFetcher.async_fetch('https://example.com', page_setup=capture_websockets)
+```
+
+You can combine it with `page_action` -- `page_setup` runs before navigation, `page_action` runs after.
+
 ### Browser Automation
 This is where your knowledge about [Playwright's Page API](https://playwright.dev/python/docs/api/class-page) comes into play. The function you pass here takes the page object from Playwright's API, performs the desired action, and then the fetcher continues.

+### Pre-Navigation Setup
+If you need to set up event listeners, routes, or scripts that must be registered before the page navigates, use `page_setup`. This function receives the `page` object and runs before `page.goto()` is called.
+
+```python
+from playwright.sync_api import Page
+
+def capture_websockets(page: Page):
+    page.on("websocket", lambda ws: print(f"WebSocket opened: {ws.url}"))
+
+page = DynamicFetcher.fetch('https://example.com', page_setup=capture_websockets)
+```
+Async version:
+```python
+from playwright.async_api import Page
+
+async def capture_websockets(page: Page):
+    page.on("websocket", lambda ws: print(f"WebSocket opened: {ws.url}"))
+
+page = await DynamicFetcher.async_fetch('https://example.com', page_setup=capture_websockets)
+```
+
+You can combine it with `page_action` -- `page_setup` runs before navigation, `page_action` runs after.
+
 ### Browser Automation
 This is where your knowledge about [Playwright's Page API](https://playwright.dev/python/docs/api/class-page) comes into play. The function you pass here takes the page object from Playwright's API, performs the desired action, and then the fetcher continues.
