Proxy Gent

The most convenient way is to use online proxy checkers, i.e. services that test all connection capabilities, including supported protocols. For example, Hidemy.name or Securitylab. As for applications, you can recommend SocksChain or Open Proxy Checker.

Yes, it is possible to use Selenium without opening a visible browser window by using headless mode. Headless mode allows the browser to run in the background without displaying the graphical user interface. This can be useful for running automated tests or web scraping processes without the overhead of a visible browser.

Here's an example of how to use headless mode with Selenium in Python:

from selenium import webdriver
from selenium.webdriver.chrome.options import Options

# Create ChromeOptions and set headless mode
chrome_options = Options()
chrome_options.add_argument('--headless')

# Create WebDriver instance with headless mode
driver = webdriver.Chrome(options=chrome_options)

# Your Selenium script...

# Close the browser when done
driver.quit()

In this example:

chrome_options.add_argument('--headless') is used to enable headless mode for Chrome.

You can apply a similar approach for other browsers like Firefox:

from selenium import webdriver
from selenium.webdriver.firefox.options import Options

# Create FirefoxOptions and set headless mode
firefox_options = Options()
firefox_options.headless = True

# Create WebDriver instance with headless mode
driver = webdriver.Firefox(options=firefox_options)

# Your Selenium script...

# Close the browser when done
driver.quit()

Headless mode is beneficial for scenarios where you don't need to visually inspect the browser while the script is running, and it can also help in improving the performance of your automated processes. Keep in mind that certain actions, especially those related to rendering and interaction with the visible browser, may behave differently in headless mode.

To reset proxy settings, you can follow these steps depending on your operating system:

For Windows:

1. Press the Windows key + R to open the Run dialog.
2. Type "inetcpl" (without quotes) and press Enter. This will open the Internet Properties window.
3. Click on the "Connections" tab.
4. Click on "LAN settings" in the bottom right corner.
5. In the "Proxy Server" section, select "Automatically detect settings" and click "OK".
6. Close the Internet Properties window.

To install a proxy server in Google Chrome, you must do the following steps:

Open the browser.
Click 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 must enter the address in the field of the protocol to which the proxy server belongs. You can get this information from the provider. Click the "OK" button to save your settings.

In simple terms, it is a logically separated part of the main local or public network. It is through it that many users can use a proxy through a single server at the same time. Each connection is allocated to a separate subnet.
