   Firefox Extended Support Release 91.0 ESR

     * New: Some of the highlights of the new Extended Support Release are:
       - A number of user interface changes. For more information, see the
         Firefox 89 release notes.
       - Firefox now supports logging into Microsoft, work, and school
         accounts using Windows single sign-on. Learn more
       - On Windows, updates can now be applied in the background while
         Firefox is not running.
       - Firefox for Windows now offers a new page about:third-party to help
         identify compatibility issues caused by third-party applications
       - Version 2 of Firefox's SmartBlock feature further improves private
         browsing. Third party Facebook scripts are blocked to prevent you
         from being tracked, but are now automatically loaded "just in time"
         if you decide to "Log in with Facebook"
       on any website.
       - Enhanced the privacy of the Firefox Browser's Private Browsing mode
         with Total Cookie Protection, which confines cookies to the site
         where they were created, preventing companis from using cookies to
         track your browsing across sites. This feature was originally
         launched in Firefox's ETP Strict mode.
       - PDF forms now support JavaScript embedded in PDF files. Some PDF
         forms use JavaScript for validation and other interactive features.
       - You'll encounter less website breakage in Private Browsing and
         Strict Enhanced Tracking Protection with SmartBlock, which provides
         stand-in scripts so that websites load properly.
       - Improved Print functionality with a cleaner design and better
         integration with your computer's printer settings.
       - Firefox now protects you from supercookies, a type of tracker that
         can stay hidden in your browser and track you
       online, even after you clear cookies. By isolating supercookies,
        Firefox prevents them from tracking your web browsing from one site
        to the next.
       - Firefox now remembers your preferred location for saved bookmarks,
         displays the bookmarks toolbar by default on new tabs, and gives you
         easy access to all of your bookmarks via a toolbar folder.
       - Native support for macOS devices built with Apple Silicon CPUs
         brings dramatic performance improvements over the non- native build
         that was shipped in Firefox 83: Firefox launches
       over 2.5 times faster and web apps are now twice as responsive (per
        the SpeedoMeter 2.0 test). If you are on a new Apple device, follow
        these steps to upgrade to the latest Firefox.
       - Pinch zooming will now be supported for our users with Windows
         touchscreen devices and touchpads on Mac devices. Firefox users may
         now use pinch to zoom on touch-capable devices to zoom in and out of
       - We’ve improved functionality and design for a number of Firefox
         search features:
         * Selecting a search engine at the bottom of the search panel now
   enters search mode for that engine, allowing you to see suggestions (if
   available) for your search terms. The old behavior (immediately performing
   a search) is available with a shift-click.
         * When Firefox autocompletes the URL of one of your search engines,
   you can now search with that engine directly in the address bar by
   selecting the shortcut in the address bar results.
         * We’ve added buttons at the bottom of the search panel to allow
   you to search your bookmarks, open tabs, and history.
       - Firefox supports AcroForm, which will allow you to fill in, print,
         and save supported PDF forms and the PDF viewer also has a new fresh
       - For our users in the US and Canada, Firefox can now save, manage,
         and auto-fill credit card information for you, making shopping on
         Firefox ever more convenient.
       - In addition to our default, dark and light themes, with this
         release, Firefox introduces the Alpenglow theme: a colorful
         appearance for buttons, menus, and windows. You can update your
         Firefox themes under settings or preferences.
     * Changed: Firefox no longer supports Adobe Flash. There is no setting
       available to re-enable Flash support.
     * Enterprise: Various bug fixes and new policies have been implemented
       in the latest version of Firefox. See more details in the Firefox for
       Enterprise 91 Release Notes.
