[HELP][Python] How to use Selenium correctly (discuss.tchncs.de)

Hi there!
So I was hoping programming might be able to help with this. I am trying to learn how to use Selenium for personal projects.

I have tried using normal, straight up selenium but it does not support authorized proxies...
I have tried SeleniumBase, but when I got it working, there were WebRTC leaks that I could not avoid.
I have tried using Undetected-chrome but that too I was unable to get authorized proxies working...
For proxies, I tried seleniumwire as well. That seems to use its own SSL certificates which unfortunately as far as I can tell is easy to detect.
Main purpose for me is web scraping and or simple login to X site, enter X info and close.

So my question is... What is the proper way to use Selenium for automating functions while avoiding detection?

Thank you in advance.

EDIT: I made this post because I am hitting a wall at every turn, and I feel like I might just be approaching this the wrong way, or maybe I'm just missing something crucial. I was hoping someone with more experience could explain to me what is the correct way of doing it without cobbling it together with duct tape.

You can do it with plain selenium all you need to set the proxy in the browser options.

from selenium import webdriver

PROXY_WITH_PORT= "111.222.333.443:8080" chrome_options = webdriver.ChromeOptions() chrome_options.add_argument(f'--proxy-server={PROXY_WITH_PORT}')

chrome = webdriver.Chrome(chrome_options=chrome_options) chrome.get("http://google.com")

In general you can pass any command like argument to the browser using options. For chrome you can find all the proxy related options here: https://www.chromium.org/developers/design-documents/network-settings/

Also if you are using the latest selenium (4.10 I think) you don’t need to point to the chromedriver executable, selenium will automatically download it if it can’t find the driver

Edit: more information about chrome arguments Edit: info about driver download

Thank you. The problem with this is that it does not support authorized proxies though. You cannot pass user:pass through it. My janky solution was to uae something like pproxy to relay the connection through my own peoxy server without user:pass. Has not been fully effective though.

I will look into doing this and using IP authorization instead of user:pass. Thank you for the help.

How is vanilla selenium with WebRTC or DNS leaks?

You might need to install your own proxy on the selenium PC and then chain that proxy to the authenticated one. Then configure the driver to use the local unauthenticated proxy

Also since Selenium just drives an actual browser the WebRTC and DNS leaks will be the browser’s responsibility not selenium. As long as you can locate elements on a page your will be ok
