Mozilla Firefox 158.0

New

• You can now fill in forms faster in Smart Window. When clicking into a form field or selecting Fill from sources, Smart Window will now suggest data to use based on your relevant open tabs and saved autofill data.
• Firefox now creates more accessible PDFs when saving a page as PDF, and when printing on Linux and macOS. This also fixes a variety of PDF rendering issues, such as missing math symbols.
• Firefox now supports the JPEG XL image format, which generally has better compression than WebP, JPEG, PNG, and GIF.
• New Tab now keeps a library of custom wallpapers under Your images, rather than only the most recent one.
• Firefox’s Translations feature now supports the following languages:
  • Albanian
  • Belarusian
  • Filipino

Fixed

• Fixed website icons (favicons) in address bar results blending into the highlight color when selecting a result with the keyboard on Ubuntu’s default theme.
• Fixed a crash that could occur while Firefox loaded website icons (favicons).
• Fixed the first letter of each search engine’s name being underlined in the Unified Search Button menu in the address bar on Windows and Linux, which could cause conflicting keyboard shortcuts.
• Fixed menus such as List all tabs, Settings, and Unified Search being hard to read with a Windows High Contrast theme. Menu background and text colors now follow the Background and Text colors chosen for a custom contrast theme in Windows Settings.
• Various security fixes.

Changed

• Firefox no longer rounds scroll positions to whole screen pixels. Scrolling is now smoother and more precise, especially on high-resolution displays or when a page is zoomed.

Web Platform

• Firefox now supports typed arithmetic in CSS calc(), allowing units to be multiplied and divided within math functions.
• Added support for the navigate option for the Notification constructor and ServiceWorkerRegistration.showNotification(), which specifies a URL to navigate to when the notification is clicked.
• The WebAuthn conditional UI is now shown on input elements with an autocomplete="webauthn" attribute. Previously, it was only shown when the attribute included another autofill field value, such as autocomplete="username webauthn". (Learn more)
• Firefox now supports the cache value for PerformanceResourceTiming.deliveryType, allowing websites to identify resources served from the HTTP cache.
• The WebGL extension EXT_polygon_offset_clamp is now available on compatible devices.

Developer

• Fixed an issue where the Network Monitor could miss WebSocket messages if they arrived immediately after a connection was established.
