Configuring Proxies Directly in Mozilla Firefox

Want to route your Firefox browsing through a proxy without messing with your entire system's network settings? While browser extensions like Proxy SwitchyOmega offer fancy management features, Mozilla Firefox has a neat trick up its sleeve: you can configure proxy settings right inside the browser itself. Let's dive into how you can set this up.

Step-by-Step: Setting Up Your Firefox Proxy

Alright, let's get this configured. First things first, you'll need Firefox installed. If you don't have it yet, you can grab it directly from Mozilla's official website. Once Firefox is ready to go, follow these steps:

1. Open Firefox. Look for the menu button (often called the "hamburger menu") in the top-right corner – it looks like three horizontal lines (1). Give it a click.

2. From the menu that appears, select Settings (2).

3. You'll land in the General panel (3). Scroll down until you find the Network Settings section. Click the Settings... (4) button within that section.

4. A "Connection Settings" window will pop up. You'll see a few options for how Firefox handles proxies. We want to set things up manually, so choose the last option: Manual proxy configuration (5).

5. Now it's time to enter your proxy details. The fields will vary slightly depending on the proxy protocol (HTTP, SOCKS, etc.). Let's use an Evomi Residential HTTP proxy as an example. Enter the hostname (like rp.evomi.com) (7) and the corresponding port (e.g., 1000 for HTTP) (8) provided in your Evomi dashboard. If you're using an HTTP proxy, it's usually a good idea to check the box "Also use this proxy for HTTPS" (6) to cover secure traffic too. Remember to use the specific hostname and port provided for your Evomi proxy plan.

6. Further down, you'll see a field labeled No proxy for (9). Here, you can list any addresses (like internal network sites or specific domains) that you want Firefox to connect to directly, bypassing the proxy. Separate multiple entries with commas.

7. Once you've entered all the details, scroll to the bottom of the window and click OK (10) to save your settings.

8. If your proxy service requires authentication (most paid services do!), the next time you try to browse, Firefox will prompt you for your proxy username and password (11). Enter the credentials provided by your proxy service (like Evomi) and click Sign in (12). You should now be browsing through your configured proxy!

Choosing the Right Proxy for Firefox

Setting up the proxy is one thing, but having a reliable proxy service is crucial. Proxies come in various types, each suited for different tasks – Residential, Datacenter, Mobile, and Static ISP proxies all have their place. At Evomi, we focus on providing high-quality, ethically sourced proxies based out of Switzerland, a country known for its stringent quality standards.

Whether you need the vast IP pool of Residential proxies (starting at just $0.49/GB) for web scraping, the speed of Datacenter proxies ($0.30/GB), the unique signature of Mobile proxies ($2.2/GB), or the stability of Static ISP proxies (from $1/IP), we've got options to fit your needs and budget. We believe in transparency and quality support, offering a different experience compared to some larger providers.

Want to see if it works for you? Evomi offers completely free trials for our Residential, Mobile, and Datacenter proxy pools, letting you test the waters before committing.

While Firefox's built-in settings are great for simple setups, remember that extensions like Proxy SwitchyOmega can offer more flexibility if you need to manage multiple proxy profiles or switch configurations frequently. But for straightforward proxy use directly in your browser, Firefox's native settings are a solid and convenient choice.
