Firefox 83.0 is now shipping as a notable update to the Mozilla web browser and this time around are some exciting changes.

Most notable with Firefox 83 is the SpiderMonkey "Warp" upgrade aiming to deliver better website responsiveness and other real-world JavaScript performance improvements. Mozilla describes the Warp benefits as "improved page load performance by up to 15%, page responsiveness by up to 12%, and reduced memory usage by up to 8%. We have replaced part of the JavaScript engine that helps to compile and display websites for you, improving security and maintainability of the engine at the same time."

  • Ending Firefox support for Flash

    On January 26, 2021, Firefox will end support for Adobe Flash, as announced back in 2017. Adobe and other browsers will also end support for Flash in January and we are working together to ensure a smooth transition for all.

    Firefox version 84 will be the final version to support Flash. On January 26, 2021 when we release Firefox version 85, it will ship without Flash support, improving our performance and security. For our users on Nightly and Beta release channels, Flash support will end on November 17, 2020 and December 14, 2020 respectively. There will be no setting to re-enable Flash support.

  • Welcoming New Contributors: Firefox 83

    With the release of Firefox 83, we are pleased to welcome all the developers who’ve contributed their first code change to Firefox in this release, 18 of whom are brand new volunteers!

  • Firefox 83 introduces HTTPS-Only Mode

    Security on the web matters. Whenever you connect to a web page and enter a password, a credit card number, or other sensitive information, you want to be sure that this information is kept secure. Whether you are writing a personal email or reading a page on a medical condition, you don’t want that information leaked to eavesdroppers on the network who have no business prying into your personal communications.

  • Firefox 83 is upon us

    Did November spawn a monster this year? In truth, November has given us a few snippets of good news, far from the least of which is the launch of Firefox 83! In this release we’ve got a few nice additions, including Conical CSS gradients, overflow debugging in the Developer Tools, enabling of WebRender across more platforms, and more besides.

  • Botond Ballo: Desktop pinch-zoom support arrives with Firefox 83

    Today is the release date of Firefox 83. One of the new features in this release is support for pinch-zooming on desktop platforms, a feature whose development I was involved with and which I’ll describe briefly in this blog post.

    Pinch gestures have long been the standard method of interaction to trigger zooming on mobile devices, and the mobile version of Firefox has supported them since (I believe) its inception.

    The desktop version of Firefox has also had a zoom feature for a long time, activated via Ctrl+Plus/Minus or Ctrl+mousewheel or a button in the UI, but importantly, this performs a different type of zooming than pinch gestures on mobile, as I’ll illustrate.

  • Mozilla Firefox 83 Now Available for Download – What’s New

    Mozilla Firefox has thus become not only an alternative to Google Chrome but to every other Chromium browser out there, and the major updates that it gets every four weeks play a key role in its effort to remain relevant in this tough battle.

    Today, Mozilla published Firefox 83, a new version of the browser for Windows, Linux, and macOS, and naturally, this one comes with massive improvements.

    First and foremost, Mozilla says it has made additional under the hood optimizations that allow for an important speed boost, especially when loading websites.

  • Bob’s 2021 Tech Predictions: What a Difference a Pandemic Makes

    I predicted that IBM would dump a big division and essentially remake itself as Red Hat, its Linux company. Well yes and no. IBM did announce a major restructuring, spinning-off Global Technology Services just as I predicted (score one for me) but it has all happened slowly because everything slows down during a pandemic. The resulting company won’t be called Red Hat (yet), but the rest of it was correct so I’m going to claim this one, not that anybody cares about IBM anymore.

  • WordPress Post Vs. Page

    Welcome back to the WordPress 101 series. In this series, we are discussing the basics of WordPress for new WordPress users. In this article, you’ll learn the differences between WordPress post vs. page. Often new users get confused between WordPress posts and pages. I remember my cousin created more than 10 pages before he realized he should’ve created posts, not pages. For new users, it may be difficult to understand why WordPress has two separate options to publish content. For them, one can create 200 pages instead of 200 posts and that should make no difference in how search engines see that content.

  • GCC's Profile Guided Optimization Performance With The Ryzen 9 5950X - Phoronix

    Given the talk in prior days around patches for PGO'ing the Linux kernel and some readers not being familiar with Profile Guided Optimizations by code compilers, here are some fresh benchmarks on a Ryzen 9 5950X looking at the benefits of applying PGO optimizations to various benchmarks. We have benchmarked GCC and Clang PGO performance many times over the years with this just being some fresh data using a Ryzen 9 5950X and the latest software stack on Ubuntu 20.10. The testing was done by first running various open-source benchmarks without PGO, repeating the tests to generate profiles for the compiler to consume with PGO, and then benchmarking those PGO-enabled builds. These numbers are about best case scenarios given that with the testing for the PGO-enabled build, the benchmarks are repeated and thus matching well to the original profile. In more real-world, general purpose scenarios it can be more difficult generating an accurate profile for your actual workflow / software usage.

    And they went and made that happen.
