Chrome 147 and Firefox 150 shipped to stable in April 2026, bringing several new web platform features. Highlights include the contrast-color() CSS function reaching Baseline (returns black or white for maximum contrast against a given color), scroll-driven animation range properties becoming Baseline, the ariaNotify() method for screen reader announcements, auto sizes for lazy-loaded images, element-scoped view transitions, the CSS border-shape property for non-rectangular borders, SVG textPath path attribute support, modulepreload for JSON and CSS modules, and Math.sumPrecise. Beta releases (Chrome 148, Firefox 151, Safari 26.5) preview name-only container queries, lazy loading for video/audio, CSS container style queries, and the :open pseudo-class.
