Proxy

This guide will walk you through setting up a proxy server in Firefox. A proxy enhances your online security and privacy by protecting your data and expanding your access to resources. We will show you two methods for setting up a proxy:

1. Method 1: Using the built-in Firefox settings menu — a simple way to configure basic settings without additional software
2. Method 2. Using a special add-on — for advanced management with quick server switching

These instructions are based on the English version of the browser for universality. The interface language can be changed at any time in the Firefox settings.

### Obtaining data for connecting to a proxy on the CyberYozh app
First, go to <a href="https://app.cyberyozh.com/proxy" target="_blank">https://app.cyberyozh.com/proxy</a>.

How to choose a proxy

Find and purchase a proxy that suits your needs. Remember two important rules:

1. Each profile requires a separate proxy
2. It is best to use <a href="https://app.cyberyozh.com/ru/blog/how-to-choose-and-buy-proxies-on-app-cyberyozh" target="_blank">private proxies</a> — they are more reliable

After purchase, you will receive login details.

After purchasing a proxy, you will receive the connection details:

- Host: Proxy IP address
- Port: Proxy port
- Proxy Username: Login
- Proxy Password: Password

Proxy example:

Host: 172.98.60.180

Port: 58763

Password: xdtAof3xB7RSmUr

Enter the IP address and port of your proxy. For SOCKS, specify the version (SOCKS4 or SOCKS5).

If necessary, add exceptions (sites that will work without a proxy) or disable the authorization request.

Click “OK” to save the changes.

If the login and password entry window does not appear, try restarting Firefox. In the window that appears, enter your username and password, then click “Log In.”

After successful authorization of the proxy server, you can check access to Internet resources, making sure that the IP address matches the proxy. You can also check the geolocation of the proxy server and the speed of the Internet connection.
