Changelog:
New
Firefox can now be set as the default system PDF viewer.
The name reported by accessibility tools for items in multi-tiered
tree controls no longer incorrectly includes information from
items at deeper levels, providing users with the correct level
of content when using a screen reader.
Fixed
Various security fixes.
Several crashes while using a screen reader were fixed including
a frequently encountered crash when using the JAWS screen
reader.
Firefox Developer Tools received significant fixes allowing
screen reader users to benefit from some of the tools that were
previously inaccessible.
SVG title and desc elements (labels and descriptions) are now
correctly exposed to assistive technology products such as
screen readers.
Changed
For users with reduced motion settings, we've reduced a number
of animations such as tab loading to reduce motion for users
with migraines and epilepsy.
The new add-ons blocklist has been enabled to improve performance
and scalability.
Enterprise
A number of bug fixes and new policies have been implemented
in the latest version of Firefox. You can see more details in
the Firefox for Enterprise 80 Release Notes.
Today's release is the final scheduled for Firefox 68 ESR
(68.12) unless there is a critical security issue found prior
to the release of Firefox ESR 78.3 on September 22, 2020. Users
of Firefox 68 ESR will be automatically upgraded to the Firefox
78 ESR series with the release of 78.3.
Developer
We've shipped an experimental sidebar panel in the inspector
to Firefox Developer Edition that helps developers more quickly
identify potential browser compatibility problems based on MDN
data.
In the Network Monitor request list, a turtle icon is shown
for "slow" requests that exceed a threshold for the waiting
time.
Firefox now supports RTX and Transport-cc for improved call
quality in poor network conditions and better bandwidth
estimation. These features also provide better compatibility
with many websites using WebRTC.
