Browsers and anti-detect browsers

For using a proxy in a browser without writing code: manual verification, account operations, multi-account isolation. This page covers each tool's fields.

Get your credentials ready

Whichever tool you use, these are the four values needed:

Firefox

Firefox is the only mainstream browser with built-in proxy authentication that needs no extension, which makes it the first choice for manual verification.

Chrome

Chrome uses the system proxy settings and cannot be configured in-browser, and an authenticated proxy triggers a dialog. Two workable approaches:

A dedicated user directory plus launch flags

# macOS
/Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome \
  --user-data-dir="$HOME/chrome-profiles/acct01" \
  --proxy-server="http://GATEWAY_HOST:58971"

# Windows (PowerShell)
& "C:\Program Files\Google\Chrome\Application\chrome.exe" `
  --user-data-dir="$env:USERPROFILE\chrome-profiles\acct01" `
  --proxy-server="http://GATEWAY_HOST:58971"

# Linux
google-chrome \
  --user-data-dir="$HOME/chrome-profiles/acct01" \
  --proxy-server="http://GATEWAY_HOST:58971"

Passwordless ports

With a fixed egress IP, ports from the Extract API need no credentials, so Chrome never prompts:

# Extract one port first
curl 'https://api.example.com/api/v1/proxy/extract?apikey=YOUR_KEY&num=1&country=US&session=sticky&time=120'
# → 1.2.3.4:20001

google-chrome \
  --user-data-dir="$HOME/chrome-profiles/acct01" \
  --proxy-server="http://1.2.3.4:20001"

Edge / Brave / other Chromium browsers

Identical to Chrome, just a different executable:

# Edge
msedge --user-data-dir="..." --proxy-server="http://GATEWAY_HOST:58971"

# Brave
brave-browser --user-data-dir="..." --proxy-server="http://GATEWAY_HOST:58971"

SwitchyOmega and other proxy extensions

Extensions avoid the command line and let you save several profiles for quick switching. With SwitchyOmega:

1. Create a new profile with type "Proxy Profile"
2. Protocol HTTP, Server GATEWAY_HOST, Port 58971
3. Click the padlock icon on the server row and enter username and password
4. Use "Auto Switch" to route by domain, so only target sites go through the proxy

Anti-detect browsers

The proxy configuration screens in anti-detect browsers (AdsPower, BitBrowser, Hubstudio, Undetectable and others) are broadly similar, and the field mapping is the same.

Common field mapping

Some tools accept a single proxy URL

Certain tools let you paste one complete URL:

http://USERNAME-country-US-session-acct01-time-120:PASSWORD@GATEWAY_HOST:58971

Align the fingerprint with the region

This is the most common mistake in anti-detect setups. An IP in the United States paired with a Chinese locale and Asia/Shanghai timezone is an obvious anomaly in itself.

When you specify country, align these too:

Static residential suits account operations better

Dynamic residential plus sticky sessions has a ceiling for account operations: time caps at 120 minutes, and the binding is to a route rather than a specific IP, so you can't recover when the exit loses that IP.

Long-running accounts should use static residential — you're buying a specific IP, fixed for a 30-day lease. Enter the host:port:user:pass you receive directly, with no session options at all.

Manual verification checklist

Once configured, check each of these in the browser:
