PyCurl Proxy

A DNS server is a remote computer that receives a domain request from a user device. And it converts it into an IP address. Sometimes it is through the DNS-server that ISPs block sites. And DNS-proxy, respectively, allows you to bypass these restrictions completely.

There are many free VPN services. But it is not safe to use them. After all, they are just engaged in parsing. That is, they collect information about users. Most often - their IP-addresses, as well as text data (these are search queries and their personal information).

Extreme RAM consumption in Firefox Selenium can be caused by a variety of factors. Here are some steps you can take to troubleshoot and resolve the issue:

1. Update Firefox and Selenium: Ensure you are using the latest versions of Firefox and Selenium, as updates often include performance improvements and bug fixes.

2. Use Firefox Options: When initializing the Firefox WebDriver, pass the -marionette option to use the Marionette protocol, which can help reduce memory usage.

from selenium import webdriver

driver = webdriver.Firefox(executable_path, options=["-marionette"])

3. Use Firefox Profile: Create a custom Firefox profile and use it with Selenium to limit memory usage.

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

profile = FirefoxProfile()
profile.set_preference("browser.sessionstore.max_tabs_undoc", 0)
profile.set_preference("browser.sessionstore.max_windows_undoc", 0)
profile.set_preference("browser.sessionstore.max_windows", 0)
profile.set_preference("browser.sessionstore.max_tabs", 0)

options = Options()
options.profile = profile

driver = webdriver.Firefox(executable_path, options=options)

4. Limit Browser Tabs: If you are using multiple tabs, try to limit the number of tabs open at the same time, as each tab consumes additional memory.

5. Disable Extensions: Disable any unnecessary browser extensions, as they can consume memory and slow down the browser.

6. Close Unused Windows: Close any unnecessary browser windows to free up memory.

7. Adjust Timeouts: Increase the implicit and explicit wait timeouts to reduce the frequency of operations that might cause memory leaks.

driver.implicitly_wait(10)
driver.set_page_load_timeout(10)

8. Use Headless Mode: Run Firefox in headless mode to reduce memory usage by not rendering the UI.

options.add_argument("--headless")

9. Monitor Memory Usage: Use tools like Task Manager (Windows) or Activity Monitor (macOS) to monitor memory usage and identify any specific tests or operations that are causing high memory consumption.

10. Profile Memory Usage: Use Firefox's built-in performance profiling tools to identify memory leaks and optimize your code.

If none of these steps resolve the issue, consider using a different browser or WebDriver, such as Chrome or Edge, which may have better memory management.

You can check it with the ping command from the command line in Windows. It is enough to enter it, with a space - the data of the proxy server (including the number of the port used) and press Enter. The reply message will tell you whether or not you have received a reply from the remote server. If not, the proxy is unavailable, respectively.

In Android to disable the proxy, you need to go to "Settings", then - "Connection and sharing", then - to "VPN". And then just deactivate the item. Many phones also provide for automatic disabling of proxies and VPNs when the device is rebooted. That is, if the user is difficult to understand the settings of the gadget, then you can trivially restart it through a long press the lock button (forced reboot).
