Question 1

How do I configure a proxy in Python Selenium?

Accepted Answer

For unauthenticated proxies: use options.add_argument('--proxy-server=http://...'). For authenticated proxies with username/password: use the selenium-wire library which handles proxy auth natively. Alternatively, create a Chrome extension to handle proxy authentication.

Question 2

Does mobile proxy help with Selenium detection?

Accepted Answer

Mobile carrier ASNs reduce the IP-level component of bot detection. The ASN class is typically the first check — carrier IPs pass this check with higher probability than datacenter ranges. Browser-level detection (headless signals, TLS fingerprint) is separate and requires additional stealth configuration.

Question 3

How do I rotate IPs in Selenium?

Accepted Answer

Call the API rotation endpoint (HTTP GET) between browser sessions. In Python: requests.get('https://api.nafeproxys.online/rotate?token=TOKEN'). Restart the WebDriver after rotation to pick up the new carrier IP.

Question 4

Can I run parallel Selenium workers with different IPs?

Accepted Answer

Yes. Provision one carrier IP per concurrent Selenium worker. Each worker operates on its own isolated routing path — no shared session detection history across parallel instances.

Question 5

Does it work with Java Selenium?

Accepted Answer

Yes. Use the org.openqa.selenium.Proxy class: proxy.setHttpProxy('gate.nafeproxys.online:PORT') and proxy.setSslProxy(...). Assign to DesiredCapabilities or ChromeOptions for Chrome-based drivers.

Question 6

What about selenium-wire or undetected-chromedriver?

Accepted Answer

Both work. selenium-wire handles proxy authentication natively without extensions. undetected-chromedriver reduces browser-level headless signals — combining it with carrier mobile IPs addresses both the browser fingerprint and ASN trust components.
