"""A Browser session manager with page pooling
|
|
|
|
:param headless: Run the browser in headless/hidden (default), or headful/visible mode.
|
|
:param block_images: Prevent the loading of images through Firefox preferences.
|
|
This can help save your proxy usage but be careful with this option as it makes some websites never finish loading.
|
|
:param disable_resources: Drop requests of unnecessary resources for a speed boost. It depends, but it made requests ~25% faster in my tests for some websites.
|
|
Requests dropped are of type `font`, `image`, `media`, `beacon`, `object`, `imageset`, `texttrack`, `websocket`, `csp_report`, and `stylesheet`.
|
|
This can help save your proxy usage but be careful with this option as it makes some websites never finish loading.
|
|
:param block_webrtc: Blocks WebRTC entirely.
|
|
:param cookies: Set cookies for the next request.
|
|
:param addons: List of Firefox addons to use. Must be paths to extracted addons.
|
|
:param humanize: Humanize the cursor movement. Takes either True or the MAX duration in seconds of the cursor movement. The cursor typically takes up to 1.5 seconds to move across the window.
|
|
:param solve_cloudflare: Solves all 3 types of the Cloudflare's Turnstile wait page before returning the response to you.
|
|
:param allow_webgl: Enabled by default. Disabling WebGL is not recommended as many WAFs now check if WebGL is enabled.
|
|
:param network_idle: Wait for the page until there are no network connections for at least 500 ms.
|
|
:param disable_ads: Disabled by default, this installs the `uBlock Origin` addon on the browser if enabled.
|
|
:param os_randomize: If enabled, Scrapling will randomize the OS fingerprints used. The default is Scrapling matching the fingerprints with the current OS.
|
|
:param wait: The time (milliseconds) the fetcher will wait after everything finishes before closing the page and returning the ` Response ` object.
|
|
:param timeout: The timeout in milliseconds that is used in all operations and waits through the page. The default is 30,000
|
|
:param page_action: Added for automation. A function that takes the `page` object, does the automation you need, then returns `page` again.
|
|
:param wait_selector: Wait for a specific CSS selector to be in a specific state.
|
|
:param geoip: Recommended to use with proxies; Automatically use IP's longitude, latitude, timezone, country, locale, and spoof the WebRTC IP address.
|
|
It will also calculate and spoof the browser's language based on the distribution of language speakers in the target region.
|
|
:param wait_selector_state: The state to wait for the selector given with `wait_selector`. The default state is `attached`.
|
|
:param google_search: Enabled by default, Scrapling will set the referer header to be as if this request came from a Google search of this website's domain name.
|
|
:param extra_headers: A dictionary of extra headers to add to the request. _The referer set by the `google_search` argument takes priority over the referer set here if used together._
|
|
:param proxy: The proxy to be used with requests, it can be a string or a dictionary with the keys 'server', 'username', and 'password' only.
|
|
:param max_pages: The maximum number of tabs to be opened at the same time. It will be used in rotation through a PagePool.
|
|
:param selector_config: The arguments that will be passed in the end while creating the final Selector's class.
|
|
:param additional_args: Additional arguments to be passed to Camoufox as additional settings, and it takes higher priority than Scrapling's settings.

|
|
:param disable_resources: Drop requests of unnecessary resources for a speed boost. It depends, but it made requests ~25% faster in my tests for some websites.
|
|
Requests dropped are of type `font`, `image`, `media`, `beacon`, `object`, `imageset`, `texttrack`, `websocket`, `csp_report`, and `stylesheet`.
|
|
This can help save your proxy usage but be careful with this option as it makes some websites never finish loading.
|
|
:param block_webrtc: Blocks WebRTC entirely.
|
|
:param cookies: Set cookies for the next request.
|
|
:param addons: List of Firefox addons to use. Must be paths to extracted addons.
|
|
:param humanize: Humanize the cursor movement. Takes either True or the MAX duration in seconds of the cursor movement. The cursor typically takes up to 1.5 seconds to move across the window.
|
|
:param solve_cloudflare: Solves all 3 types of the Cloudflare's Turnstile wait page before returning the response to you.
|
|
:param allow_webgl: Enabled by default. Disabling WebGL is not recommended as many WAFs now check if WebGL is enabled.
|
|
:param network_idle: Wait for the page until there are no network connections for at least 500 ms.
|
|
:param disable_ads: Disabled by default, this installs the `uBlock Origin` addon on the browser if enabled.
|
|
:param os_randomize: If enabled, Scrapling will randomize the OS fingerprints used. The default is Scrapling matching the fingerprints with the current OS.
|
|
:param wait: The time (milliseconds) the fetcher will wait after everything finishes before closing the page and returning the ` Response ` object.
|
|
:param timeout: The timeout in milliseconds that is used in all operations and waits through the page. The default is 30,000
|
|
:param page_action: Added for automation. A function that takes the `page` object, does the automation you need, then returns `page` again.
|
|
:param wait_selector: Wait for a specific CSS selector to be in a specific state.
|
|
:param geoip: Recommended to use with proxies; Automatically use IP's longitude, latitude, timezone, country, locale, and spoof the WebRTC IP address.
|
|
It will also calculate and spoof the browser's language based on the distribution of language speakers in the target region.
|
|
:param wait_selector_state: The state to wait for the selector given with `wait_selector`. The default state is `attached`.
|
|
:param google_search: Enabled by default, Scrapling will set the referer header to be as if this request came from a Google search of this website's domain name.
|
|
:param extra_headers: A dictionary of extra headers to add to the request. _The referer set by the `google_search` argument takes priority over the referer set here if used together._
|
|
:param proxy: The proxy to be used with requests, it can be a string or a dictionary with the keys 'server', 'username', and 'password' only.
|
|
:param max_pages: The maximum number of tabs to be opened at the same time. It will be used in rotation through a PagePool.
|
|
:param selector_config: The arguments that will be passed in the end while creating the final Selector's class.
|
|
:param additional_args: Additional arguments to be passed to Camoufox as additional settings, and it takes higher priority than Scrapling's settings.
