    Responses


Firefox Extended Support Release 91.0 ESR

  o 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'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
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.

  o Changed: Firefox no longer supports Adobe Flash. There is no setting
    available to re-enable Flash support.
  o 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.

  o CVE-2021-29986: Race condition when resolving DNS names could have led to
    memory corruption
