## CDP / UC helpers

| Method | Description |
|--------|-------------|
| `activate_cdp_mode()` | Enables CDP domains. |
| `execute_cdp(method)` | Sends a CDP command. |
| `execute_cdp_with_params(method, params)` | Sends a CDP command with params. |
| `cdp_mouse_click(x, y)` | CDP mouse click at viewport coordinates. |
| `cdp_insert_text(text)` | CDP text insert into whatever has focus (`cdp_type_text` is the deprecated old name). |
| `cdp_click(selector)` | Scroll the element into view and click its centre through CDP. |
| `cdp_click_element(selector)` | Deprecated: use `cdp_click`. |
| `cdp_fast_type(selector, text)` | Clear and insert text in one operation (fast, not stealthy). |
| `cdp_wait_for_element_present(selector, timeout)` | Wait for an element to appear in the DOM. |
| `cdp_select_option_by_index(selector, index)` | Select a dropdown option by zero-based index. |
| `open_new_tab_url(url)` | Open a new tab and navigate to `url`. |
| `clear_browser_cache()` | Clears cache. |
| `clear_browser_cookies()` | Clears cookies. |
| `get_cookies()` | Returns cookies as JSON. |
| `set_network_conditions(conditions)` | Network throttling. |
| `set_timezone(id)` | Sets timezone. |
| `set_geolocation(lat, lon, acc)` | Sets geolocation. |
| `uc_click(selector)` | Stealth click with delay. |
| `uc_type(selector, text)` | Stealth type with delay. |
| `uc_open_with_reconnect(url)` | Opens `url` after reconnecting the session. |
| `install_addon(path, temporary)` | Firefox only: installs an add-on (an `.xpi` file or an unpacked directory on the machine geckodriver runs on) through geckodriver and returns its id. An unsigned add-on needs `temporary = true`. Other browsers get `Unsupported`; use `with_extension_dir` for Chrome. |
| `uninstall_addon(id)` | Firefox only: removes an add-on by the id `install_addon` returned. |
| `uc_open_with_disconnect(url)` | Opens `url` with a fresh session. |
