Article Summaries:

  • In January 2026, Chrome 144 and Firefox 147 entered stable releases, bringing several new baseline web platform features. Firefox added CSS Anchor Positioning and the Navigation API, while Chrome introduced the ::search-text pseudo‑element, a declarative for location access, the Temporal API for robust date handling, and the caret‑shape property. Both browsers also enhanced view transitions, with Firefox adding SPA‑specific transition types and an activeViewTransition property. Beta releases followed: Chrome 145 added text‑justify, column layout tweaks, and onanimationcancel, and Firefox 148 introduced Location.ancestorOrigins for iframe origin checks. These updates expand styling, navigation, and date APIs for developers.
