Firefox Developer Tools Integrations

Mozilla Firefox is a free, open-source web browser developed by the Mozilla Foundation, a non-profit organization dedicated to internet health and privacy. Designed to prioritize user privacy and security, Firefox offers features like Total Cookie Protection, which provides outstanding privacy by default. The browser includes tools such as Firefox View, allowing users to see tabs open on other devices and access recent history, and built-in PDF editing capabilities, enabling form edits directly within the browser. Available across various platforms, including Windows, macOS, Linux, Android, and iOS, Firefox ensures a consistent and secure browsing experience. Its commitment to user-centric development and transparency makes it a preferred choice for those seeking a trustworthy alternative to proprietary browsers.

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.
