Proxy Helper Setup: Step by Step

Proxy Helper is a Chrome extension, listed in the Chrome Web Store by the developer henices, that sets Chrome's proxy: HTTP, HTTPS, SOCKS4 or SOCKS5, a PAC script, or auto-detect. It keeps a bypass list, a proxy login, and several profiles, each a complete setup with its own proxy and login. The toolbar popup switches between them; it changes only Chrome's traffic.

For per-site rules with many proxies, SwitchyOmega or FoxyProxy also fit; for a list of saved locations, Proxy Switcher.

1. Install Proxy Helper from its Chrome Web Store listing (Add to Chrome) and pin its icon. The options page opens after the install; later, press Alt+O or choose Options from the icon's menu.

2. On the General tab, under HTTP Proxy, enter host gate.proxyfield.io and Port 7000. Leave Proxy Mode on single proxy, and leave HTTPS Proxy and SOCKS Proxy empty.

3. Under Authentication, enter your ProxyField Username (with the location, such as <login>-country-us-city-new_york) and Password. These are your proxy credentials from the account, not your account login.
4. In Bypass list, keep <local> and add localhost, 127.0.0.1, then save.
5. Click the toolbar icon, open your profile and click its HTTP entry.

6. Load https://api.ipify.org: it shows the proxy's IP, not yours. https://ipinfo.io/json shows its city and country.

What to expect: no password box appears, because Proxy Helper answers Chrome's sign-in request for the proxy itself (Chrome's onAuthRequired event). If a box does appear, see the next section.

Proxy Helper supplies the login from the active profile every time Chrome asks for it, so a prompt after a restart means the extension did not answer. Check these causes in order:

The fix that ends the prompt for good: the IP allowlist. With ProxyField you can authenticate by IP instead of username and password, so Chrome never asks:

1. Add your public IP to the allowlist in your ProxyField account.
2. In Proxy Helper, empty the Username and Password fields, set Port under HTTP Proxy to the port you set up in the dashboard, and save.
3. Click the HTTP entry in the popup and load https://api.ipify.org.

The allowlist fits a fixed home or office IP; if your own IP changes, update the list. With the IP allowlist, the product, location and session are set per port in the dashboard. More in proxy authentication and 407 Proxy Authentication Required.

Profiles make country switching a one-click job: each profile holds its own proxy and login, and the location sits in the username.

1. Set up the first profile as above, with <login>-country-us-city-new_york, and Rename it "New York".
2. Duplicate it, rename the copy (for example "Germany"), and change only the Username: <login>-country-<code> with the country's code. Countries take their two-letter code in lowercase, as in <login>-country-de.
3. Switch from the popup, or press Alt+P for the next profile, and reload the page.

Targeting covers 195+ countries and 21,000+ cities: country, region (state) and city, all 50 US states. A username without a session gives a new IP on every request; a session keeps one IP for 30 s to 36 h (presets 1, 5, 10, 30 min, 1, 3, 6 h). Region, session and session time go in the same username: -region-<region>, -session-<id> and -ttl-<seconds> (30 to 129,600 seconds, 20 minutes by default), as in <login>-country-us-region-new_york-city-new_york-session-he9f2qga-ttl-600; every part after the login is optional. Residential is the default; add -mobile after the login for mobile IPs: <login>-mobile-country-us. All locations: proxy locations.

SOCKS5: Chrome sends no username and password to a SOCKS5 proxy, so Authentication does not apply: add your IP to the allowlist in your ProxyField account first, then fill SOCKS Proxy with gate.proxyfield.io and the port you set up in the dashboard, and choose SOCKS5. SOCKS5 with a username and password runs on gate.proxyfield.io:7000, but Chrome cannot send them. More on SOCKS5: SOCKS5 proxies.

PAC script: a PAC script picks a proxy or a direct connection per URL. A minimal one that sends one site through ProxyField and everything else direct:

function FindProxyForURL(url, host) {
  if (dnsDomainIs(host, ".example.com")) return "PROXY gate.proxyfield.io:7000";
  return "DIRECT";
}

Paste it under PAC → PAC script, save, and choose the PAC Script entry in the popup. The login under Authentication answers the HTTP proxy the script returns. PAC modes ignore Rules Mode.

Gateway error messages: 407 Proxy Authentication Required for a wrong login or password, an IP not on the allowlist or a malformed location, 402 Payment Required when no traffic is left and 502 Bad Gateway when no exit could be connected; a restricted site gets no separate response, and a 403 comes from the site itself. Status codes are explained in proxy errors. To test a line before you enter it, use the proxy checker. Our 24/7 live chat helps with setup and integration. Chrome's own proxy options are on proxy settings in Chrome.

Use ProxyField for lawful work within our acceptable use policy. A browser extension moves only Chrome's traffic and is not a VPN (proxy vs VPN).
