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 webpages.
  - We&#8217;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&#8217;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 look.
  - 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.

MFSA 2021-33 (bsc#1188891):

* CVE-2021-29986: Race condition when resolving DNS names could have led to
  memory corruption
* CVE-2021-29981: Live range splitting could have led to conflicting
