Subject: [mozilla-wikimedia-discuss] Firefox Quantum is in Beta
To: mozilla-wikimedia-discuss(a)mozilla.com
Cc: Harald Kirschner <harald(a)mozilla.com>
Dear Wikimedia,
This year Mozilla has been working on our most significant release,
possibly ever. Firefox Quantum is going into Beta today [1]. It will be
shipping to users on November 14, 2017 as a major upgrade of Firefox’s
internals, building the foundation to make Firefox faster with every
release after. We’ve been actively testing these improvements in our
Nightly channel with great results.
To make sure that we have not regressed Wikimedia properties but made them
faster, we would like your help in testing Firefox Beta. In particular
we’re interested in differences in rendering or functionality inadvertently
introduced and any impact on performance metrics.
One of the major components of Firefox Quantum is Quantum CSS [2]. This new
CSS engine takes advantage of modern hardware, parallelizing work across
multiple cores. Some websites may depend on assumptions about the ordering
and timing of events that occur during the browser's rendering cycle,
particularly on page load.
If you discover any issues, please report them to us through Bugzilla [3]
or reach out via our discuss mailing list. We are also here to help,
like setting up Firefox in your automated testing, running performance
benchmarks, or any other questions you have about the web & Firefox.
Thanks for helping us push the web forward.
Adam Stevenson
