About

Welcome to your new favorite browser. Get the latest features, fast performance, and the development tools you need to build for the open web. All the latest developer tools in beta, plus experimental features like the multi-line console editor and WebSocket inspector. A separate profile and path so you can easily run it alongside release or beta Firefox. Preferences tailored for web developers, browser and remote debugging are enabled by default, as are the dark theme and developer toolbar button. Firefox DevTools now grays out CSS declarations that don’t have an effect on the page. When you hover over the info icon, you’ll see a useful message about why the CSS is not being applied, including a hint about how to fix the problem. The new Firefox DevTools are powerful, flexible, and best of all, hackable. This includes a best-in-class JavaScript debugger, which can target multiple browsers and is built in React and Redux.

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.
