#CVE-2021-29968: Out of bounds read when drawing text characters onto a Canvas
89.0
New
* Say hello to a fresh new Firefox, designed to get you where you want to go
even faster. We??ve redesigned and modernized the core experience to be
cleaner, more inviting, and easier to use.
Beginning in 89, you??ll notice a number of changes, including:
Simplified browser chrome and toolbar: Less frequently used items removed
to focus on the most important navigation items.

Clear, streamlined menus: Re-organized and prioritized menu content
according to usage. Updated labels and removed iconography.

Updated prompts: Infobars, panels, and modals have a cleaner design and
clearer language.

Inspired tab design: Floating tabs neatly contain information and surface
cues when you need them, like visual indicators for audio controls. The
rounded design of the active tab supports focus and signals the ability to
easily move the tab as needed.

Fewer interruptions: Reduced number of alerts and messages, so you can
browse with fewer distractions.
Cohesive, calmer visuals: Lighter iconography, a refined color palette, and
more consistent styling throughout.
This release also includes enhancements to our privacy offerings:
+ We??ve 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 companies from using cookies to
track your browsing across sites. This feature was originally launched
in Firefox??s ETP Strict mode.
* For macOS users, we're introducing the elastic overscroll effect known from
many other applications. A gentle bouncing animation will indicate that you
reached the end of the page.
In addition, we added support for smart zoom. Double-tap with two fingers
on your trackpad, or with a single finger on your Magic Mouse, to zoom the
content below your cursor into focus.
* Native context menus: Context menus on macOS are now native and support
Dark Mode.

* WebRender is now enabled on Linux with the NVIDIA binary driver and on all
desktop environments
#
Fixed
* Colors in Firefox on macOS will no longer be saturated on wide gamut
displays, untagged images are properly treated as sRGB, and colors in
images tagged as sRGB will now match CSS colors.
* In full screen mode on macOS, moving your mouse to the top of the screen
will no longer hide your tabs behind the system menu bar.
* Also in full screen mode on macOS, it is now possible to hide the browser
toolbars for a fully immersive full screen experience. This brings macOS in
line with Windows and Linux.
* Various stability and security fixes.
#
Changed
* Introducing a non-native implementation of web form controls, which
delivers a new modern design and some improvements to page load
performance. Watch for layout bugs in web pages that make assumptions about
the dimensions or styling of form controls.
* The screenshots feature is available in the right-click context menu. You
can also add a screenshots shortcut to your toolbar. Learn more.
