Mozilla Firefox — is one of the few browsers that allows you to configure a proxy separately from the entire operating system. This is a killer feature for those who want to route browser traffic through a secure channel (e.g., USA) while keeping games and messengers working directly (for low ping).
In this guide, we will break down two configuration methods (built-in and via FoxyProxy) and, most importantly, explain what type of proxy you need for your tasks.
Part 1. Which proxy to choose for Firefox?
Before diving into the settings, choose the right "fuel." Firefox is a versatile browser, and its tasks can vary.
1. Datacenter Proxies — For content and speed
- What it is: IP addresses of hosting providers.
- What it's for: Secure access to international content (YouTube, Netflix, LinkedIn), file downloading, and protected web surfing.
- Pro: They are the cheapest and fastest. Ideal for regular web surfing.
2. Residential Proxies (ISP) — For shopping and work
- What it is: IP addresses of home internet providers.
- What it's for: Shopping in foreign stores (iHerb, Amazon, Nike), working with payment systems, and registering accounts.
- Pro: You look like a regular home user, which ensures high reliability and connection stability.
3. Mobile Proxies (4G/5G) — For SMM and social media
- What it is: IPs of mobile operators.
- What it's for: Securely managing your social media presence or separating work and personal profiles.
- Nuance: It's best to use them with privacy extensions to manage your digital footprint and increase anonymity.

Part 2. Data Preparation
For the setup, we will need data from a reliable provider. We recommend CyberYozh App — we provide proxies with UDP support.
After purchasing, you will receive:
- IP (Host):
172.98.60.180 - Port:
58763 - Login / Password: Authorization data.

Part 3. Method 1: Built-in Browser Configuration (No extensions)
This method is suitable if you have one proxy and want to use it constantly.
Open the Firefox menu (three bars in the upper right corner) -> Settings.

- For HTTP proxy: Enter the IP and Port in the HTTP Proxy field. Check the box "Also use this proxy for HTTPS".
- For SOCKS5 (Recommended): Enter the IP and Port in the SOCKS Host field. Select the SOCKS v5 radio button.
- Important: In the "No proxy for" field, delete everything unnecessary if you want to proxy absolutely everything. And check the box "Proxy DNS when using SOCKS v5" — this will protect you from DNS leaks.

- Try opening any website. The browser will ask for a Login and Password. Enter the data from your personal account.

Verification: Go to whoer.net or browserleaks.com and make sure the IP has changed.

Part 4. Method 2: Configuration via FoxyProxy
If you have several proxies or need to switch between countries quickly, built-in settings are inconvenient. It is better to use the FoxyProxy Standard extension.
Step 1. Installation
Go to the Firefox Add-ons store.

- Click Save.
