Firefox 159, released October 27, 2026, adds several convenience features and fixes across desktop platforms. On macOS, sharing now uses the system share picker, including page previews and recent contacts, and can share multiple tabs; apps that use the default browser for sign-in now open Firefox when it is set as default. Saved passwords appear in the sidebar by default. Smart Window can monitor pages for changes such as price drops or restocks and send desktop notifications, though availability is rolling out gradually. Users can search open tabs with Ctrl/Cmd+Shift+A, and the AI page-summary feature now sends the page address to the chatbot provider rather than truncated page text.

The update also resolves issues involving memory growth on minimized Zoom pages and Linux map views, video rendering with NVIDIA HDR, Chrome bookmark imports, file-upload folder selection, and tabs detaching under Wayland, among other fixes and security updates. For developers, the Web Console permits redeclaring let, const, and class variables, while web-platform additions include scroll-driven animations, scoped custom-element registries, new WebGL extensions, and changes to HTML sanitization. Firefox also improves display of web addresses in several writing systems. Windows 8.1 and earlier, and macOS 10.14 and earlier, are no longer supported by the standard release; users on those systems are directed to Firefox ESR.
