100.0 Release Note
https://www.mozilla.org/en-US/firefox/100.0/releasenotes/
Hello, we’re excited to release the 100th version of Firefox!
Thank you to everyone who got us here: To every employee past and present
who played a role in delivering Firefox—thank you for your grit and hard work.
To every contributor who championed open source, thank you for turning a
browser into a movement!
Finally, thanks to every user of Firefox—thank you most of all. We didn’t
get here—17 years and 100 versions later—without your support. Your choice
to use Firefox contributes directly to a better web, keeping it open and
accessible to all. It is with a profound sense of gratitude and appreciation
that we will continue fighting for this global public resource, putting
people over profits.

New︰
We now support captions/subtitles display on YouTube, Prime Video, and
Netflix videos you watch in Picture-in-Picture. Just turn on the subtitles on
the in-page video player, and they will appear in PiP.
Picture-in-Picture now also supports video captions on websites that use
https://support.mozilla.org/en-US/kb/about-picture-picture-firefox
WebVTT (Web Video Text Track) format, like Coursera.org, Canadian
Broadcasting Corporation, and many more.
On the first run after install, Firefox detects when its language does
not match the operating system language and offers the user a choice between
the two languages.
Firefox spell checking now checks spelling in multiple languages. To
https://support.mozilla.org/en-US/kb/how-do-i-use-firefox-spell-checker
enable additional languages, select them in the text field’s context menu.
HDR video is now supported in Firefox on Mac—starting with YouTube!
Firefox users on macOS 11+ (with HDR-compatible screens) can enjoy
higher-fidelity video content. No need to manually flip any preferences to
turn HDR video support on—just make sure battery preferences are NOT set to
“optimize video streaming while on battery”.
Hardware accelerated AV1 video decoding is enabled on Windows with
supported GPUs (Intel Gen 11+, AMD RDNA 2 Excluding Navi 24, GeForce 30).
Installing the AV1 Video Extension from the Microsoft Store may also be
required. https://bit.ly/3kxy8my
Video overlay is enabled on Windows for Intel GPUs, reducing power usage
during video playback.
Improved fairness between painting and handling other events. This
noticeably improves the performance of the volume slider on Twitch.

Scrollbars on Linux and Windows 11 won't take space by default. On Linux,
users can change this in Settings. On Windows, Firefox follows the system
setting (System Settings > Accessibility > Visual Effects > Always show
scrollbars).
Firefox now supports credit card autofill and capture in the United
Kingdom.
https://support.mozilla.org/en-US/kb/credit-card-autofill
Firefox now ignores less restricted referrer policies—including
unsafe-url, no-referrer-when-downgrade, and origin-when-cross-origin—for
cross-site subresource/iframe requests to prevent privacy leaks from the
referrer.
Fixed︰
Users can now choose preferred color schemes for websites. Theme authors
can now make better decisions about which color scheme Firefox uses for
menus. Web content appearance can now be changed in Settings.
Beginning in this release, the Firefox installer for Windows is signed
with a SHA-256 digest, rather than SHA-1. Update KB4474419 is required for
successful installation on a computer running Microsoft Windows 7. For more
details about this update, visit the Microsoft Technical Support website.

In macOS 11+ we now only rasterize the fonts once per window. This means
that opening a new tab is fast, and switching tabs in the same window is also
fast. (There's still work to do to share fonts across windows, or to reduce
the time it takes to initialize these fonts.)
The performance of deeply-nested display: grid elements is greatly
improved.
Support for profiling multiple java threads has been added.
Soft-reloading a web page will no longer cause revalidation for all
resources.
Non-vsync tasks are given more time to run, which improves behavior on
Google docs and Twitch.
Geckoview APIs have been added to control the start/stop time of
capturing a profile.
Changed︰
Firefox has a new focus indicator for links which replaces the old dotted
outline with a solid blue outline. This change unifies the focus indicators
across form fields and links, which makes it easier to identify the focused
link, especially for users with low vision.
New users can now set Firefox as the default PDF handler when setting
Firefox as their default browser.
Some websites might not work correctly in Firefox version 100 due to
Firefox's new three-digit number. You can read about it in our blog post here!

See the Mozilla Support article Difficulties opening or using a website
in Firefox 100 for possible workarounds you can use. There, you will also
find instructions for reporting a broken website so that Mozilla can help fix
the problem.

Enterprise︰
Various bug fixes and new policies have been implemented in the latest
version of Firefox. You can find more information in the Firefox for
Enterprise 100 Release Notes.

Developer︰

Web Platform︰
Support for the WritableStream API has landed. WritableStreams provide an
interface for writing streaming data to a sink object.
Additionally, ReadableStream gained support for the “pipeTo” method,
which allows you to connect a ReadableStream to a WritableStream. For
example, this would allow you to process data retrieved using “fetch” with
the WritableStream Sink object.
Support for WASM Exceptions is now available. This allows C++ exception
handling and unwinding/destructing semantics to be expressed in WASM without
an additional JavaScript helper code—and at zero cost to code that does not
rely on exception semantics.
