Live Reload is a Firefox extension designed for web developers, enabling real-time monitoring and reloading of HTML, CSS, and JavaScript files. This subscription-based tool offers a seamless experience by automatically refreshing the page or selectively reloading only the modified stylesheets when changes are detected. With its configurable rules, users can easily set parameters for monitoring included scripts, stylesheets, and frames, streamlining the development process significantly.

The extension also includes a debugging feature accessible through the developer tools, allowing users to troubleshoot any issues with their monitoring rules. However, it is important to note that due to security restrictions, files accessed via the file system cannot be monitored directly. A recommended workaround is to serve local files over HTTP using platforms like Python, NodeJS, or PHP, ensuring a smooth workflow for developers.
