Question How can I use Selenium WebDriver in Java to load a specific Chrome user profile? System.setProperty("webdriver.chrome.driver", "path/to/chromedriver.exe");ChromeOptions options = new ChromeOptions();options.addArguments("user-data-dir=path/to/your/profile");WebDriver driver = new ChromeDriver(options); Answer Loading a specific Chrome profile in Selenium WebDriver allows you to utilize previous browsing data, extensions, and configurations. This can be useful for testing features in a user-specific environment. import org.openqa.selenium.WebDriver;import org.openqa.selenium.chrome.ChromeDriver;import org.openqa.selenium.chrome.ChromeOptions;public class LoadChromeProfile { public static void main(String[] args) { // Set the path for ChromeDriver System.setProperty("webdriver.chrome.driver", "path/to/chromedriver.exe"); // Create an instance of ChromeOptions ChromeOptions options = new ChromeOptions(); // Specify the user data directory (Chrome profile path) options.addArguments("user-data-dir=path/to/your/profile"); // Initialize the WebDriver with ChromeOptions WebDriver driver = new ChromeDriver(options); // Navigate to a website to check if the profile is loaded driver.get(" // Close the driver driver.quit(); }} Causes Incorrect path to the Chrome profile directory Not setting the necessary Chrome options ChromeDriver version mismatch with the installed Chrome version Solutions Ensure you provide the correct path to the user data directory.

Binary to make the websocket request.Microsoft EdgeListen I know that's not Chrome, but hear me out. Because Edge is based on Chromium, the same trick works. Here's a blog post by @wunderwuzzi23 with all the details.Multiple ProfilesIf you want to extract the Chrome cookies for a profile other than the Default profile, just edit the PROFILE variable in cookie_crimes.py. This uses some sneaky "writing to /tmp" tricks to trick Chrome into reading the cookies for us.How it worksHeadless Chrome and user-data-dirHeadless (no window is rendered) Chrome is allowed to specify a user-data-dir. This directory contains cookies, history, preferences, etc. By creating a new headless Chrome instance, and specifying the user-data-dir to be the same as the victim's, your headless Chrome instance will authenticate as the vicitm.Remote debuggingFrom here, we just use a normal (but extremely forbidden and undocumented) feature of Chrome: the Remote Debugging protocol. This is how Chrome Developer Tools communicate with Chrome. Once your headless Chrome (with remote debugging enabled) instance is running, this code just executes remote debugging commands to print the user's cookies for all websites in plaintext.You can fully control Chrome at this point, taking any action the user could take.closing ceremonydon't do crimes with this please
