Firefox proxy settings enable users to improve online privacy, access geo-restricted content, and enhance security. By routing internet traffic through a proxy server, users can mask their IP address and protect sensitive data from potential threats. This feature is particularly useful for those who value anonymity or need to bypass regional restrictions during their browsing sessions.

Firefox supports various proxy configuration methods, including system integration, auto-detection, and manual setup. This guide will help you configure proxies and choose the best type for your needs.
