Firefox Smart Window beta adds free AI assistant with three model choices on MacOS and Windows
↗
Mozilla's Firefox Smart Window beta integrates a free AI assistant offering three selectable model categories and context-aware browsing features, currently available only on MacOS and Windows in Firefox 153 or later.
Only one feed covers this, so corroboration is limited. For engineers on MacOS or Windows, Smart Window provides a browser-native AI assistant with per-chat model switching and memory controls at no cost, though Linux users are left waiting.
