Proxy for Common Crawl

Simply, in the connection properties of your PC or mobile device, you need to enter the data of the proxy server through which you will be connecting. In Windows, for example, this is done through "Settings", then "Network and Internet", and in the next window you should open the tab "Proxy server".

If Selenium is not working correctly with Firefox, there are several potential reasons and troubleshooting steps you can take to resolve the issue. Here are some common solutions:

1. Update Selenium WebDriver and Firefox:

   • Ensure that you are using the latest version of Selenium WebDriver and Firefox. Compatibility issues between different versions could cause problems.

2. Check Firefox Browser Version:

   • Verify that your Firefox browser is up to date. Selenium WebDriver may not be fully compatible with outdated browser versions.

3. Download the Latest GeckoDriver:

   • Make sure you are using the latest version of GeckoDriver (the WebDriver for Firefox). Download it from the official GeckoDriver releases page and ensure it is in your system's PATH or provide its path explicitly in your Selenium script.

4. Use the Correct GeckoDriver Version:

   • Ensure that you are using a GeckoDriver version compatible with the Firefox version installed on your machine. Check the Mozilla GeckoDriver documentation for compatibility information.

5. Specify GeckoDriver Path Explicitly:

   • Explicitly set the path to the GeckoDriver executable when creating the WebDriver instance in your Selenium script:

var options = new FirefoxOptions();
options.AddArgument("--headless");  // Optional: Run Firefox in headless mode
options.AddArgument("--disable-gpu");  // Optional: Disable GPU acceleration

using (var driver = new FirefoxDriver("path/to/geckodriver", options))
{
    // Your Selenium script
}

6. Check Browser Configuration:

   • Some Selenium features may require specific browser configurations. For example, headless mode may require additional options. Adjust your Firefox options as needed.

7. Firefox Profile Configuration:

   • If you use a custom Firefox profile, ensure that your profile settings are compatible with your Selenium script. You can create a new profile or use the default one.

8. Check for Firewall/Antivirus Issues:

   • Firewalls or antivirus software might block the connection between Selenium and Firefox. Temporarily disable these to check if they are causing the issue.

9. Run Firefox in Headless Mode:

   • If you are facing issues with the graphical interface, try running Firefox in headless mode to see if the problem persists.

10. Browser Console Logs:

    • Check the browser console logs for any error messages. Open the browser console (Ctrl + Shift + J) while running your Selenium script and look for relevant messages.

11. Run a Basic Script:

    • Create a minimal Selenium script to open Firefox and navigate to a simple website. This helps isolate the issue and determine whether it's related to your specific script or a more general problem.

12. Reinstall Firefox:

    • If all else fails, consider reinstalling Firefox. This can help ensure that the browser installation is in a clean and functional state.

By going through these steps and addressing any identified issues, you should be able to troubleshoot and resolve problems with Selenium not working correctly with Firefox.

In Selenium, you can check if the DOM of a page is loaded by using JavaScriptExecutor. Here's how you can check:

from selenium import webdriver

driver = webdriver.Chrome()
driver.get("http://www.example.com")

while True:
    try:
        driver.execute_script("return document.readyState")
        if driver.execute_script("return document.readyState") == "complete":
            print("Page is loaded")
            break
    except Exception as e:
        print("Exception occurred")

In this script, the document.readyState property is used to check if the page is loaded or not. In JavaScript, the "complete" value of document.readyState indicates that the page is loaded.

This script will keep running until the page is loaded. Once the page is loaded, it will print "Page is loaded" and break the loop.

Please note that this script assumes that the page is completely loaded when document.readyState is "complete". However, this is not always the case. Sometimes, some elements may still be loading even when document.readyState is "complete". So, it's better to use explicit or implicit waits to wait for specific elements to be present or visible.

To check if the proxy server is working, follow these steps:

1. Open your web browser or software that uses the proxy server.

2. Visit a website that displays your public IP address, such as whatismyip.com.

3. Before making any changes to your browser or software settings, take note of your current IP address.

4. Configure your browser or software to use the proxy server you've chosen. If you're unsure how to do this, refer to the instructions provided in the previous answer.

5. Refresh the page with the IP address displayer (e.g., whatismyip.com).

6. Compare the new IP address displayed on the page to the one you noted earlier. If the IP address has changed, the proxy server is working correctly.

Alternatively, you can use a proxy checker tool or website that tests your proxy server's connection and anonymity. Keep in mind that some proxy servers may not work with certain websites or services, so you may need to try different proxies to find one that works for your specific needs.

The main task is to monitor traffic on the local network, as all requests will be handled by an organized proxy. Most often it is used to block access to certain resources in offices.
