What is a Firefox Proxy?

A proxy is a program that acts as an intermediary between your computer and the internet. It’s not a must-have, though some (ISP) internet service providers or organizations may require you to use one when using the Internet.

It sends all your requests to the Internet on your computer’s behalf and retrieves back the results to your computer. Proxies improve your Internet performance, filter out undesirable requests, and improve your overall online security by hiding your computer from the Internet.

Configuring Proxy Settings

Installing a Mozilla proxy will shield your computer from the malware that is found online. There are various ways to configure proxy settings in order to get the protection that you are looking for.

The setup of each process is straightforward.

1.   When using Automatic Proxy Configuration URL

If your organization or institution has provided you with a URL to automatically set up a proxy for that particular network, use this proxy setup process.

  • Open the Firefox menu.
  • Click  Options
  • When this section opens, scroll down to the Network tab
  • Click on the network settings button
  • In the connection settings section, tick the checkbox for “auto-detect proxy settings for this network” to activate the “Automatic proxy configuration URL” field where you can type the address of your institution or organization. For example http://static.aaaaa.ac.xx/proxies/internal.pac
  • Click the OK button to close the Connection Settings and save your configurations.

You can as well use the other connection options including ‘Use system proxy settings or ‘No Proxy’ depending on your network setting requirements.

2.   If you choose the Manual Proxy Configuration

For “Manual proxy configuration”, you’ll be required to enter proxy server settings like IP address and port number.

Your organization or company’s network administrator will provide you with the required network proxy server address and port number for configuration.

In order to configure the settings manually, first open Firefox and go to “connection settings”. Follow these other steps.

1.        Tick the checkbox labeled “manual proxy configuration” to active its field

2.        In the “HTTP Proxy” text field, type the network proxy server address

3.        You’ll also be needed to click and enter the port for the proxy server in the “Port” text field next to the ‘HTTP Proxy' box.

4.        Make sure to check “Use the proxy server for all protocols”. Firefox will use the HTTP proxy server for File Transfer Protocol (FTP) connections and also SSL-encrypted HTTPS connections.

If you want a SOCKS proxy, type its address in the “SOCKS Host” and its port into the “Port” box.

For SOCKS proxy, enter 127.0.0.1 as the address and the port number.

Firefox browser will relay your traffic through the default proxy server running on your computer. Mozilla Firefox uses SOCKS v5 to connect. Click SOCKS v4 when your SOCKS proxy is using an older standard instead. When not sure, always leave it as SOCKS v5.

Fixing Failure to Connect to a Proxy

Firefox can fail to access a proxy server. This happens when you configure your browser with incorrect proxy server details. Software or a virus can also be the cause of this problem.

To fix the problem, try to disable it, according to this guide.  Check if you have configured the settings very well.

If the problem still persists, I recommend that you perform one of these troubleshooting techniques to find a solution;

  • Scan your PC for a proxy server virus. A good antivirus will detect and remove the malware
  • Reset internet options. Being unable to connect to a network proxy can be caused by incorrect internet settings
  • Clear the cache of your Firefox browser
  • Consider restoring your computer to a previously working restore point
  • Remove recently installed software. Some software can interfere with proxy settings

I hope this works.

Benefits you get from Proxy Servers

Proxy servers will help you browse the internet anonymously. If your preferences are on privacy and security, get one that supports full data encryption.

Anonymity and privacy are not the only reasons to use a proxy. Other benefits include the following;

  • To protect your sensitive data from falling in hands of cybercriminals. Your personal information can be used to commit crimes or sold in black markets. Use a proxy to keep your data safe while on the internet
  • A proxy blocks web trackers
  • Use a proxy to unblock restricted content in some countries
  • Proxies help to block dangerous or inappropriate content
