Proxy SwitchyOmega is a highly useful Firefox extension, especially for users who frequently need to switch between proxies. The interface is clean and easy to navigate, making it simple to configure and switch between different proxy settings without having to manually adjust the browser's network settings every time. Whether you're a developer, need to bypass restrictions, or often work in different network environments, this extension is a must-have. It supports various proxy protocols and runs smoothly—definitely worth recommending!
