Mozilla ☛ Under the hood: How Firefox suggests tab groups with local AI
Mozilla launched Tab Grouping in early 2025, allowing tabs to be arranged and grouped with persistent labels. It was the most requested feature in the history of Mozilla Connect. While tab grouping provides a great way to manage tabs and reduce tab overload, it can be a challenge to locate which tabs to group when you have many open.

Removing XSLT from Chromium
Mason Freed and Dominik Röttsches have published a document with a timeline and plans for removing Extensible Stylesheet Language Transformations (XSLT) from the Chromium project and Chrome browser:
Chromium has officially deprecated XSLT, including the XSLTProcessor JavaScript API and the XML stylesheet processing instruction. We intend to remove support from version 155 (November 17, 2026). The Firefox and WebKit projects have also indicated plans to remove XSLT from their browser engines. This document provides some history and context, explains how we are removing XSLT to make Chrome safer, and provides a path for migrating before these features are removed from the browser.LWN covered the Web Hypertext Application Technology Working Group (WHATWG) discussion about XSLT in August.
