FoxyProxy & SwitchyOmega

Browser extensions are the fastest way to use a proxy for manual work: checking ads in another country, reviewing localised search results, testing a geo-redirect. They switch the proxy for the whole browser (or for matching URLs) with one click.

FoxyProxy (Firefox, Chrome, Edge)#

FoxyProxy supports authenticated HTTP and SOCKS5 proxies in both Firefox and Chromium browsers.

1. Install FoxyProxy Standard from the browser's add-on store.
2. Open the extension Options → Proxies → Add.
3. Fill in:

4. Save, then pick the proxy from the toolbar menu.

For residential, add one entry per location you use, each with its own username: px4k2m9q7a-country-fr, px4k2m9q7a-country-de-city-munich, and so on. Add -session-<8 characters>-ttl-30 to keep the same IP while you browse.

Patterns#

In Proxy by Patterns mode, only matching URLs go through the proxy:

*.example.fr/*          → FR mobile – Orange
*://*.google.de/*       → DE residential

Everything else uses your normal connection, which keeps unrelated tabs fast and saves residential traffic.

SwitchyOmega and ZeroOmega (Chromium)#

The original SwitchyOmega is no longer maintained and does not run on recent Chrome versions (Manifest V3). ZeroOmega is a maintained fork with the same interface.

1. New profile → Proxy Profile, name it.
2. Protocol HTTP, server fr.mobile.gw.proxuno.com, port 10421.
3. Click the lock icon next to the server to enter username and password.
4. Apply changes, then select the profile from the toolbar.

Chromium's extension API cannot authenticate SOCKS5 proxies. For SOCKS5 in Chrome, use HTTP instead, or IP whitelist and leave the credentials out.

Auto Switch#

An Auto Switch profile routes by hostname, like FoxyProxy patterns. Combine one profile per country with rules such as *.amazon.de → DE residential.

Rotation from the browser#

Bookmark the mobile proxy's rotation link. Opening it rotates the IP and shows the new address as JSON. Then reload the page you were testing.

Pitfalls#

• WebRTC can reveal your real IP even behind a proxy. Disable non-proxied UDP in the extension (FoxyProxy and ZeroOmega both have an option) or use a WebRTC-blocking extension.
• Sticky residential sessions last 30 minutes at most. If a site logs you out mid-session, the session ended and the IP changed — start a new session id.
• Credentials are stored in the browser profile. Do not sync that profile to shared machines.
• Extensions only affect that browser. Other apps on the machine keep using your normal connection.
