Stable browser releases

Chrome 144 and Firefox 147 released to stable during January. This post takes a look at the many new features this month, with several things becoming Baseline Newly available.

Note: Browser compatibility data pulled from MDN is included in these posts and may not have been updated yet for very recent browser releases. The post will show the correct information as soon as it appears in the browser-compat-data release.

CSS Anchor Positioning

Firefox 147 includes support for CSS Anchor Positioning, making this feature Baseline Newly available. This API lets you position elements relative to other elements, known as anchors. This is useful for tooltips, menus, and popovers, where you want an element to be positioned relative to another element on the page.

Find-in-page styling with ::search-text

Chrome 144 includes the ::search-text pseudo-element. This feature exposes find-in-page search result styling to authors as a highlight pseudo-element, similar to ::selection and ::spelling-error. This lets you customize the appearance of search results when a user uses the browser's find-in-page functionality.

The <geolocation> element

Chrome 144 introduces the <geolocation> element, a declarative, user-activated control for accessing the user's location. It streamlines the user and developer journey by handling the permission flow and directly providing location data to the site, often eliminating the need for a separate JavaScript API call.

The Temporal API

Chrome 144 includes the Temporal API. This provides standard objects and functions for working with dates and times. This is a significant addition to JavaScript, offering a robust and modern replacement for the Date object.

View Transition enhancements

Firefox 147 includes identifying view transition types. These provide a mechanism by which different types can be specified for active view transitions. CSS can then be used to apply animations to DOM elements when their content updates, depending on the transition type specified. Firefox 147 adds support for single-page app (SPA) view transition types only, not cross-document view transition types.

Beta browser releases

Beta browser versions give you a preview of things that will be in the next stable version of the browser. It's a great time to test new features, or removals, that could impact your site before the world gets that release. New betas this month are Chrome 145 and Firefox 148.

Chrome 145 includes the text-justify property to control justification methods, and improvements to multi-column layout with column-wrap and column-height. It also brings the onanimationcancel event to GlobalEventHandlers. Additionally, customizable <select> is extended to listboxes.

Firefox 148 includes support for Location.ancestorOrigins, allowing you to determine if a document is embedded in an <iframe> and by which sites.
