Aggiornamento Firefox 158.0 per Mac, Windows e Linux

Aggiornamento Firefox 158.0 per Mac, Windows e LinuxRilasciato l'aggiornamento alla versione 158.0 del noto browser Firefox.

A questo link sono pubblicate le note di rilascio di questa nuova versione con l'elenco di tutte le novità, in particolare:


Nuovo
  • You can now fill 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.

    This feature is part of a progressive roll out.

    What is a progressive roll out?

    Certain new Firefox features are released gradually. This means some users will see the feature before everyone does. This approach helps to get early feedback to catch bugs and improve behavior quickly, meaning more Firefox users overall have a better experience.

  • New Tab now keeps a library of custom wallpapers under Your images, rather than only the most recent one.

  • Firefox now supports the new JPEG XL image format which generally has better compression than WebP, JPEG, PNG and GIF and is designed to supersede them.

  • The tab bar can now be shown at either the top or bottom of the screen on Firefox for Android. Check Settings -> Customize to configure.


Risolto
  • Menus such as the List all tabs menu, the Settings menu, and Unified Search menu are now visually consistent on Windows with a High Contrast theme. The user is now able to customize menu background color and text color when creating a custom theme in Windows Settings by setting Background and Text, respectively.

  • PDF generation (for saving as PDF and also printing on Linux and macOS) now uses SkPDF. This allows PDFs to be more accessible, and also fixes a variety of PDF rendering issues.

  • 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.


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


Web Platform
  • 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 will now be shown on input elements with an autocomplete="webauthn" attribute. Previously, the UI would only be shown on input elements with additional autofill field values, e.g. autocomplete="username webauthn".

  • Firefox now supports the cache value for PerformanceResourceTiming.deliveryType, allowing websites to identify resources served from the HTTP cache.

  • Firefox now supports typed arithmetic in CSS calc(), allowing units to be multiplied and divided within math functions.

  • The WebGL extension EXT_polygon_offset_clamp is now available on compatible devices.
