Firefox
Firefox is Mozilla's open-source web browser available for Windows, Mac, Linux, iOS, and Android, built on the Gecko rendering engine independently of Google's Chromium project. Its developer tools include a CSS Grid and Flexbox inspector, accessibility checker, JavaScript debugger, network monitor, and multi-account containers for isolating sessions per website or client. Firefox's Enhanced Tracking Protection blocks third-party trackers, fingerprinters, and cryptominers by default. As the only major browser engine not based on Chromium, Firefox is essential for cross-browser testing and for developers who want their sites to work outside the Blink rendering engine. It is the preferred browser for frontend developers who value privacy and want the most complete set of built-in developer tools.

Safari is Apple's native web browser built on the WebKit rendering engine, available on Mac and iOS. On Apple Silicon Macs and iPhones, Safari consistently achieves the best battery life of any browser due to deep hardware and OS integration. Its Web Inspector provides a full suite of developer tools including a JavaScript debugger, responsive design simulator, network inspector, and CSS coverage analysis. For any developer building web applications intended for iOS users, Safari is essential for testing — it is the only browser engine permitted on the App Store, meaning all third-party iOS browsers also use WebKit. Safari's Intelligent Tracking Prevention blocks cross-site tracking cookies by default, requiring attention from developers building analytics and authentication systems.
