Positive Proxy

It depends on how you plan to log in to Facebook. For example, if on a PC, just specify the proxy server settings in the connection properties or in the browser settings. If on a mobile (site or application), you need to specify the proxy data in the settings of the phone itself. Or you can install an application that allows you to automatically set up a VPN connection.

Updating CoreML models in an iOS app typically involves fetching a new model file, parsing it, and then updating the CoreML model with the new version. JSON parsing can be used to extract necessary information from the fetched JSON file. Below is a step-by-step guide using Swift:

Fetch and Parse JSON

Fetch a JSON file containing information about the updated CoreML model, including its download URL, version, etc.

import Foundation

// Replace with the URL of your JSON file
let jsonURLString = "https://example.com/model_info.json"

if let url = URL(string: jsonURLString),
   let data = try? Data(contentsOf: url),
   let json = try? JSONSerialization.jsonObject(with: data, options: []) as? [String: Any] {

    // Extract information from the JSON
    if let newModelURLString = json["new_model_url"] as? String,
       let newModelVersion = json["new_model_version"] as? String {
        // Continue with the next steps
        updateCoreMLModel(with: newModelURLString, version: newModelVersion)
    }
}

Download and Save New Model:

Download the new CoreML model file from the provided URL and save it locally.

func updateCoreMLModel(with modelURLString: String, version: String) {
    guard let modelURL = URL(string: modelURLString),
          let modelData = try? Data(contentsOf: modelURL) else {
        print("Failed to download the new model.")
        return
    }

    // Save the new model to a local file
    let documentsDirectory = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask).first!
    let newModelURL = documentsDirectory.appendingPathComponent("newModel.mlmodel")

    do {
        try modelData.write(to: newModelURL)
        print("New model downloaded and saved.")
        updateCoreMLModelWithNewVersion(newModelURL, version: version)
    } catch {
        print("Error saving new model: \(error.localizedDescription)")
    }
}

Update CoreML Model:

Load the new CoreML model and update the app's model.

import CoreML

func updateCoreMLModelWithNewVersion(_ modelURL: URL, version: String) {
    do {
        // Load the new CoreML model
        let newModel = try MLModel(contentsOf: modelURL)

        // Replace the existing CoreML model with the new version
        // Assuming your model has a custom CoreMLModelManager class
        CoreMLModelManager.shared.updateModel(newModel, version: version)

        print("CoreML model updated to version \(version).")
    } catch {
        print("Error loading new CoreML model: \(error.localizedDescription)")
    }
}

Handle Model Updates in App:

Depending on your app's architecture, you might want to handle the model update in a dedicated manager or service. Ensure that you handle the update gracefully and consider user experience during the update process.

Make sure to replace placeholder URLs and customize the code according to your actual implementation. Additionally, handle errors appropriately and test thoroughly to ensure a smooth update process.

To disable WebRTC in Chrome using Selenium ChromeDriver in C#, you can use ChromeOptions to set the necessary command-line arguments. Here's an example:

using OpenQA.Selenium;
using OpenQA.Selenium.Chrome;

class Program
{
    static void Main()
    {
        ChromeOptions chromeOptions = new ChromeOptions();

        // Disable WebRTC
        chromeOptions.AddArgument("--disable-webrtc");

        // Other options (customize as needed)
        // chromeOptions.AddArgument("--use-fake-device-for-media-stream");
        // chromeOptions.AddArgument("--use-fake-ui-for-media-stream");

        IWebDriver driver = new ChromeDriver(chromeOptions);

        // Your Selenium script...

        driver.Quit();
    }
}

In this example:

--disable-webrtc is added as a command-line argument to disable WebRTC in Chrome.

Additional options related to WebRTC are provided in comments. Uncomment and customize them based on your specific requirements.

Make sure to replace the "Your Selenium script..." comment with the actual logic of your Selenium script.

To run Firefox with Selenium and connected extensions, you'll need to use the FirefoxDriverService and FirefoxOptions. You can also set the path to the Firefox executable and the path to the extensions' .xpi files using the FirefoxBinary and FirefoxProfile classes. Here's an example of how to do this:

Install the required NuGet packages:

Install-Package OpenQA.Selenium.Firefox.WebDriver -Version 3.141.0
Install-Package OpenQA.Selenium.Support.UI -Version 3.141.0

Create a method to add extensions to the Firefox profile:

using OpenQA.Selenium;
using OpenQA.Selenium.Firefox;
using System.IO;
using System.Linq;

public static IWebDriver CreateFirefoxDriverWithExtensions(string[] extensionPaths)
{
    var firefoxOptions = new FirefoxOptions();
    var firefoxBinary = new FirefoxBinary(Path.GetDirectoryName(FirefoxDriverService.DefaultServicePath));
    var firefoxProfile = new FirefoxProfile();

    // Add extensions to the Firefox profile
    foreach (var extensionPath in extensionPaths)
    {
        var extensionFile = new FileInfo(extensionPath);
        if (extensionFile.Exists)
        {
            firefoxProfile.AddExtension(extensionPath);
        }
    }

    firefoxOptions.BinaryLocation = firefoxBinary.Path;
    firefoxOptions.Profile = firefoxProfile;

    // Start the FirefoxDriverService with the specified Firefox binary
    var driverService = FirefoxDriverService.CreateDefaultService(firefoxBinary.Path, FirefoxDriverService.DefaultPort);
    driverService.EnableVerboseLogging = true;

    // Create the FirefoxDriver with the specified options
    var driver = new FirefoxDriver(driverService, firefoxOptions);

    return driver;
}

Use the CreateFirefoxDriverWithExtensions method in your test code:

using OpenQA.Selenium;
using System;

namespace SeleniumFirefoxExtensionsExample
{
    class Program
    {
        static void Main(string[] args)
        {
            // Paths to the extensions' .xpi files
            string[] extensionPaths = new[]
            {
                @"path\to\extension1.xpi",
                @"path\to\extension2.xpi"
            };

            // Create the FirefoxDriver with connected extensions
            using (var driver = CreateFirefoxDriverWithExtensions(extensionPaths))
            {
                // Set up the WebDriver
                driver.Manage().Window.Maximize();

                // Navigate to the target web page
                driver.Navigate().GoToUrl("https://www.example.com");

                // Perform any additional actions as needed

                // Close the browser
                driver.Quit();
            }
        }
    }
}

In this example, we first create a method called CreateFirefoxDriverWithExtensions that takes an array of extension paths as input. Inside the method, we set up the FirefoxOptions, FirefoxBinary, and FirefoxProfile to include the specified extensions. Then, we start the FirefoxDriverService with the specified Firefox binary and create the FirefoxDriver with the specified options.

In the test code, we call the CreateFirefoxDriverWithExtensions method with the paths to the extensions' .xpi files and use the returned IWebDriver instance to interact with the browser.

Remember to replace "path\to\extension1.xpi" and "path\to\extension2.xpi" with the actual paths to the extensions' .xpi files you want to connect.

A proxy server spoofs the IP address, port, and hardware information. It can also act as a secure gateway for data transmission in an already encrypted form (for example, this is how a proxy with the SOCKS5 protocol works).
