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 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 allow_webgl: Enabled by default. Disabling it WebGL not recommended as many WAFs now checks 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: Enabled by default, this installs `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 timeout: The timeout in milliseconds that is used in all operations and waits through the page. The default is 30000 :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, & 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`. 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 for 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 adaptor_arguments: The arguments that will be passed in the end while creating the final Adaptor's class.
