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’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.
* 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.
