LinkedIn Proxy

Both on a PC and on modern cell phones, a built-in utility that is responsible for working with network connections, provides the ability to set up a connection through a proxy server. You just need to enter the IP-address for connection and the port number. In the future all traffic will be redirected through this proxy. Accordingly, the provider will not block it.

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 JavaScript with Selenium, you can save and reuse cookies using the WebDriver's manage().getCookies() and manage().addCookie() methods. Here's a simple example:

const { Builder } = require('selenium-webdriver');
const firefox = require('selenium-webdriver/firefox');

// Create a new instance of the Firefox driver
const driver = new Builder()
  .forBrowser('firefox')
  .setFirefoxOptions(new firefox.Options().headless())
  .build();

// Navigate to a webpage
async function navigateToPage() {
  await driver.get('https://example.com');
}

// Save cookies
async function saveCookies() {
  const cookies = await driver.manage().getCookies();
  // Save the cookies to a file or some storage mechanism
  // For simplicity, we'll just print them here
  console.log('Cookies:', cookies);
}

// Reuse cookies
async function reuseCookies(savedCookies) {
  // Delete existing cookies
  await driver.manage().deleteAllCookies();

  // Add the saved cookies to the browser session
  for (const cookie of savedCookies) {
    await driver.manage().addCookie(cookie);
  }

  // Navigate to a page to apply the cookies
  await navigateToPage();
}

// Example usage
(async () => {
  await navigateToPage(); // Navigate to the page and set some initial cookies

  await saveCookies(); // Save the cookies

  // Close and reopen the browser or navigate to a different page
  // ...

  // Reuse the saved cookies
  await reuseCookies(savedCookies);
})();

The navigateToPage function navigates to a webpage and sets some initial cookies.

The saveCookies function retrieves the current cookies using manage().getCookies() and prints them. You would typically save them to a file or some storage mechanism.

The reuseCookies function deletes existing cookies, then adds the saved cookies back to the browser session using manage().addCookie(). It then navigates to a page to apply the cookies.

The example usage section demonstrates how to use these functions in a sequence.

In PlayStation 4 and 5, setting up a proxy server follows a similar algorithm. It is necessary to go to the "Library", select "Settings", open the tab "Network Settings". In the window that appears, click on "Network". Then choose the type of connection you are using. It will be offered to set the DHCP, DNS and then the proxy server parameters step by step. And here you can enable it by manually entering the necessary settings.

To enable proxies in your MacBook, you need to go to "System Preferences" (from the "Apple" menu), then open "Network", then - specify the type of connection you are using. Then select "Advanced Settings" (can be named as "Advanced"), then click on "Proxy". And then - either set the parameters manually, or specify a configuration file.
