### Hypothetical Questions

**BrowserConfig:**

1. **Browser Types and Headless Mode**
   - *"How do I choose between `chromium`, `firefox`, or `webkit` for `browser_type`?"*
   - *"What are the benefits of running the browser in `headless=True` mode versus a visible UI?"*

2. **Managed Browser and Persistent Context**
   - *"When should I enable `use_managed_browser` for advanced session control?"*
   - *"How do I use `use_persistent_context` and `user_data_dir` to maintain login sessions and persistent storage?"*

3. **Debugging and Remote Access**
   - *"How do I use the `debugging_port` to remotely inspect the browser with DevTools?"*

4. **Proxy and Network Configurations**
   - *"How can I configure a `proxy` or `proxy_config` for region-specific crawling or authentication?"*

5. **Viewports and Layout Testing**
   - *"How do I adjust `viewport_width` and `viewport_height` for responsive layout testing?"*

6. **Downloads and Storage States**
   - *"What steps do I need to take to enable `accept_downloads` and specify a `downloads_path`?"*
   - *"How can I use `storage_state` to preload cookies or session data?"*

7. **HTTPS and JavaScript Settings**
   - *"What happens if I set `ignore_https_errors=True` on sites with invalid SSL certificates?"*
   - *"When should I disable `java_script_enabled` to improve speed and stability?"*

8. **Cookies, Headers, and User Agents**
   - *"How do I add custom `cookies` or `headers` to every browser request?"*
   - *"How can I set a custom `user_agent` or use a `user_agent_mode` like `random` to avoid detection?"*

9. **Performance Tuning**
   - *"What is the difference between `text_mode`, `light_mode`, and adding `extra_args` for performance tuning?"*

10. **Content Extraction and Filtering**
    - *"How does the `word_count_threshold` affect which pages or sections get processed?"*
    - *"What `extraction_strategy` should I use for structured data extraction and how does `chunking_strategy` help organize the content?"*
    - *"How do I apply a `css_selector` or `excluded_tags` to refine my extracted content?"*

11. **Markdown and Text-Only Modes**
    - *"Can I generate Markdown output directly and what `markdown_generator` should I use?"*
    - *"When should I set `only_text=True` to strip out non-textual content?"*

12. **Caching and Session Handling**
    - *"How does `cache_mode=ENABLED` improve performance, and when should I consider `WRITE_ONLY` or disabling the cache?"*
    - *"What is the role of `session_id` in maintaining state across requests?"*

13. **Page Loading and Timing**
    - *"How do `wait_until`, `page_timeout`, and `wait_for` elements help control page load timing before extraction?"*
    - *"When should I disable `wait_for_images` to speed up the crawl?"*

14. **Delays and Concurrency**
    - *"How do `mean_delay` and `max_range` randomize request intervals to avoid detection?"*
    - *"What is `semaphore_count` and how does it manage concurrency for multiple crawling tasks?"*

15. **JavaScript Execution and Dynamic Content**
    - *"How can I inject custom `js_code` to load additional data or simulate user interactions?"*
    - *"When should I use `scan_full_page` or `adjust_viewport_to_content` to handle infinite scrolling?"*

16. **Screenshots, PDFs, and Media**
    - *"How do I enable `screenshot` or `pdf` generation to capture page states?"*
    - *"What are `image_description_min_word_threshold` and `image_score_threshold` for, and how do they enhance image-related extraction?"*

17. **Logging and Debugging**
    - *"How do `verbose` and `log_console` help me troubleshoot issues with crawling or page scripts?"*
