SwitchyOmega is a free and open-source Firefox extension designed to simplify proxy configuration for web developers and IT professionals. It provides a user-friendly interface that replaces the traditional proxy settings dialog, allowing users to manage multiple proxies effortlessly. With features such as one-click switching from a popup menu and automatic proxy selection based on website rules, SwitchyOmega enhances browsing efficiency and usability.

The extension supports HTTP/HTTPS proxy authentication and allows for flexible configurations, including fixed servers and customizable profiles. Users can review and modify proxy settings for resources that fail to load, ensuring a smooth browsing experience. SwitchyOmega is free of ads and malware, focusing solely on proxy management, but it requires users to supply their own trusted proxy servers to function effectively.
