Selenium Proxy Configuration: Python Tutorial

Selenium Proxy Setup

Configure proxies in Selenium for automated browser testing and scraping.

TL;DR: Use Chrome Options to set proxy settings, then pass to WebDriver. For authenticated proxies, use extensions or wire protocol.

Basic Chrome Setup

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

proxy = "proxy.nobleproxy.com:8080"

chrome_options = Options()
chrome_options.add_argument(f'--proxy-server=http://{proxy}')

driver = webdriver.Chrome(options=chrome_options)
driver.get('https://httpbin.org/ip')

With Authentication (selenium-wire)

pip install selenium-wire

from seleniumwire import webdriver

proxy_options = {
    'proxy': {
        'http': 'http://username:password@proxy.nobleproxy.com:8080',
        'https': 'http://username:password@proxy.nobleproxy.com:8080'
    }
}

driver = webdriver.Chrome(seleniumwire_options=proxy_options)
driver.get('https://httpbin.org/ip')

Firefox Setup

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

profile = webdriver.FirefoxProfile()
profile.set_preference("network.proxy.type", 1)
profile.set_preference("network.proxy.http", "proxy.nobleproxy.com")
profile.set_preference("network.proxy.http_port", 8080)
profile.set_preference("network.proxy.ssl", "proxy.nobleproxy.com")
profile.set_preference("network.proxy.ssl_port", 8080)

driver = webdriver.Firefox(firefox_profile=profile)

Best Practices

1. Handle proxy errors gracefully
2. Implement retry logic
3. Close drivers properly
4. Use headless mode when appropriate
