About Firefox Developer Tools is a set of web developer tools built into Firefox. You can use them to examine, edit, and debug HTML, CSS, and JavaScript. This section contains detailed guides to all of the tools as well as information on how to debug Firefox for Android, how to extend DevTools, and how to debug the browser as a whole. You can open the Firefox Developer Tools from the menu by selecting Tools > Web Developer > Web Developer Tools or use the keyboard shortcut Ctrl + Shift + I or F12 on Windows and Linux, or Cmd + Opt + I on macOS.	About HtmlUnit is a "GUI-Less browser for Java programs" that models HTML documents and provides an API to interact with web pages, such as invoking pages, filling out forms, and clicking links, similar to a standard web browser. It offers fairly good JavaScript support, which is constantly improving and is capable of handling complex AJAX libraries, simulating browsers like Chrome, Firefox, or Edge depending on the configuration used. Typically used for testing purposes or retrieving information from websites, HtmlUnit is not a generic unit testing framework but is intended to simulate a browser within another testing framework such as JUnit or TestNG. It is utilized as the underlying "browser" by various open source tools like WebDriver, Arquillian Drone, and Serenity BDD, and is employed by many projects for automated web testing, including Apache Shiro, Apache Struts, and Quarkus.
