New︰

    Firefox keeps getting faster as a result of significant updates to
SpiderMonkey, our JavaScript engine, you will now experience improved page
load performance by up to 15%, page responsiveness by up to 12%, and reduced
memory usage by up to 8%. We have replaced part of the JavaScript engine that
helps to compile and display websites for you, improving security and
maintainability of the engine at the same time.

    Firefox introduces HTTPS-Only Mode. When enabled, this new mode ensures
https://blog.mozilla.org/security/?p=2632
that every connection Firefox makes to the web is secure and alerts you when
a secure connection is not available. You can enable it in Firefox
Preferences.

    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.

    Picture-in-Picture now supports keyboard shortcuts for fast forwarding
and rewinding videos: use the arrow keys to move forward and back 15 seconds,
along with volume controls. For a list of supported commands see Support
Mozilla

    When you are presenting your screen on a video conference in Firefox, you
will see our improved user interface that makes it clearer which devices or
displays are being shared.

    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.

    Our users in India on the English build of Firefox will now see Pocket
recommendations in their new tab featuring some of the best stories on the
web. If you don’t see them, you can turn on Pocket articles in your new tab
by following these steps.

    For the recently released Apple devices built with Apple Silicon CPUs,
you can use Firefox 83 and future releases without any change. This release
(83) will support emulation under Apple’s Rosetta 2 that ships with macOS
                     https://www.apple.com/rosetta/index.html
Big Sur. We are working toward Firefox being natively-compiled for these CPUs
in a future release.

    This is a major release for WebRender as we roll out to more Firefox
users on Windows 7 and 8 as well as on macOS 10.12 to 10.15.

Fixed︰

    This release also includes a number of accessibility fixes:
        ．Screen reader features which report paragraphs now correctly report
paragraphs instead of lines in Google Docs
        ．When reading by word using a screen reader, words are now correctly
reported when there is punctuation nearby
        ．The arrow keys now work correctly after tabbing in the
picture-in-picture window

    For users on macOS restoring a session with minimized windows, Firefox
now uses much less power and you should see much longer battery life.

progress outward from the center.
