DevTools Deep Dive
summary
Live demo of Firefox DevTools shows exact features and how they behave: CSS-selector search and element cycling, color picker with eyedropper and instant hex/HSL/RGBA toggles, debugger file search and console that logs real objects and supports CSS-styled messages, network inspector that reports transfer vs disk size and full timing breakdown (queued/blocked/waiting), performance profiler with color-coded events, responsive mode simulating touch, CSS Grid overlays and a draggable cubic‑Bezier animation editor — all built into Developer Edition and shown working.
