Firefox Developer Tools
Firefox Developer Tools is a set of web development and debugging utilities built directly into the Mozilla Firefox browser. It allows developers to inspect, edit, and debug HTML, CSS, and JavaScript on web pages in real-time, as well as analyze network activity, performance, and accessibility. These tools are essential for front-end development, testing, and optimizing web applications.
Developers should use Firefox Developer Tools when building or debugging web applications, as it provides deep insights into page structure, styling, and behavior with features like the Inspector, Console, and Debugger. It is particularly valuable for cross-browser testing, performance profiling, and accessibility auditing, helping ensure web compatibility and user experience. The tools are free, open-source, and integrate seamlessly with Firefox's developer-focused features like CSS Grid and Flexbox inspectors.
