A2enmod Proxy

In the upper right corner of the browser, click "Settings and Other", and then select the "Options" tab in the window that appears. Once the "General" window opens, locate the "Advanced" tab and click "Open proxy settings" in the menu that appears. Here, in the line "Use a proxy server", select "On". In the "Address" field, you must specify the IP address of the proxy, and in the "Port" field - the port of the proxy. The last thing to do is to click "Save".

To configure a proxy on your MikroTik router, you need the Winbox software. The following steps must be done in the application: Open the "IP"-"WebProxy" sections. Check the box next to "Enabled". Enter the parameters of the proxy-server.

After that you have to specify the data of the proxy in the browser to be used. As an example, let's take Google Chrome. What you need to do:

Open the browser.
Click on the icon "?" in the upper right corner.
Go to "Settings".
Select the "Advanced" option.
Click the "System" tab.
Click on "Open proxy settings for your computer".
Click on "Network settings".
Activate the "Use proxy server" option.
In the tab that opens, specify the IP address of the proxy server. You should enter it in the field of the protocol to which the proxy server belongs.
Click the "OK" button to save your settings.

Using MetaMask in Selenium involves interacting with the MetaMask extension within a browser controlled by Selenium WebDriver. Below is an example using Python and Chrome WebDriver to automate MetaMask interactions

1. Install Required Packages

Make sure you have Selenium and the appropriate WebDriver for your browser installed. You can install them using:

pip install selenium

Download the ChromeDriver executable and make sure it's in your system's PATH or provide the path explicitly.

2. Install MetaMask Extension

Ensure that the MetaMask extension is installed in your browser. You can install it from the Chrome Web Store.

3. Example Script

Here's a basic example script using Python and Chrome WebDriver to interact with MetaMask:

from selenium import webdriver
from selenium.webdriver.common.by import By
import time

# Create a WebDriver instance (assuming Chrome in this example)
driver = webdriver.Chrome()

try:
    # Navigate to a website that uses MetaMask (e.g., a dApp)
    driver.get("https://example.com")

    # Wait for MetaMask to load (adjust wait time based on your system and network speed)
    time.sleep(5)

    # Find and click the MetaMask extension icon
    metamask_icon = driver.find_element(By.CSS_SELECTOR, ".icon-container")
    metamask_icon.click()

    # Switch to the MetaMask popup window
    driver.switch_to.window(driver.window_handles[-1])

    # Perform MetaMask interactions (e.g., login, transaction)
    # Example: Find and click the "Connect" button
    connect_button = driver.find_element(By.XPATH, "//button[contains(text(), 'Connect')]")
    connect_button.click()

    # Wait for MetaMask interactions to complete (adjust wait time based on your actions)
    time.sleep(5)

    # Close the MetaMask popup window
    driver.close()

    # Switch back to the original window
    driver.switch_to.window(driver.window_handles[0])

    # Continue with other actions on the original website

finally:
    # Close the browser window
    driver.quit()

4. Customize the Script

Customize the script based on the specific MetaMask actions you want to perform. For example, you might need to handle MetaMask login, transaction confirmations, etc.

Use appropriate locators (CSS selectors, XPaths, etc.) to identify MetaMask elements.

Adjust wait times based on your system and network speed.

5. Execute the Script

Run the script, and it should automate interactions with MetaMask while navigating a website that integrates MetaMask functionality.

Remember that browser automation, including interacting with extensions like MetaMask, should be done responsibly and in compliance with the terms of service of the websites and extensions involved. Automated interactions with MetaMask might trigger security measures, so use such automation for testing and development purposes only.

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.

First you should check if its characteristics are correct. Some proxy servers are just IP address and port number, others use so called "connection script". You need to double-check that the data was entered correctly.
