Firefox proxy setup

Protocols

HTTP with a login in the built-in settings; SOCKS5 with a login only through an extension

UDP

No. WebRTC can send UDP around the proxy

Where the setting is

Settings → General → Proxy settings → Configure proxy (older versions: Network Settings → Settings…)

Works with

Residential and mobile proxies

Before you start

• Your proxy login and password from the Residential or Mobile page of the dashboard, and traffic on that product.
• The setting belongs to the current Firefox profile, not to the computer. To keep your usual browsing direct, create a second profile in about:profiles and set the proxy there.
• The SOCKS Host field has no place for a login, and our gateway needs one. Use HTTP on port 7000 in the built-in settings, or FoxyProxy for SOCKS5 on port 7001.

Add the proxy

1. Open Settings, stay on General, scroll to Proxy settings at the bottom and click Configure proxy. Typing "proxy" into the settings search finds it too. The Connection Settings window opens.
2. Under Configure Proxy Access to the Internet, choose Manual proxy configuration.
3. Enter gate.aeonproxy.com in HTTP Proxy and 7000 in Port, and tick Also use this proxy for HTTPS. Leave SOCKS Host empty.
4. Tick Do not prompt for authentication if password is saved and click OK.
5. Open any site. Firefox says the proxy is requesting a username and password: enter your login with its keys and your password, and let Firefox save them when it offers.

The tick in step 3 copies the host and port 7000 into HTTPS Proxy. In Firefox that field is the proxy for HTTPS sites, not a TLS connection to the proxy, so it stays on port 7000. Once the login is saved and the box in step 4 is ticked, Firefox signs in to the proxy without asking.

Check the proxy

Open the IP checker. It should show the country you asked for and an address that is not yours. If the WebRTC card shows your real address, open about:config and set media.peerconnection.ice.proxy_only_if_behind_proxy to true: WebRTC then connects only through the proxy when the page itself came through one. This is an advanced setting that Mozilla does not document, and it can stop WebRTC calls from connecting, so run the IP checker again to confirm the result. Setting media.peerconnection.enabled to false turns WebRTC off entirely, which also ends video calls in the browser. More in WebRTC leaks.

Rotating or sticky

For browsing, use a sticky login: all connections keep one IP for up to 60 minutes, then the same line moves to a new IP in Germany. A rotating login changes the IP with every new connection, and sites often sign you out when that happens.

To switch to another login, Firefox has to forget the saved one: remove the saved login for gate.aeonproxy.com in about:logins, restart Firefox and enter the new login when it asks.
