Mozilla has released Version 53.0 of the Firefox browser.
53.0
Firefox Release

April 19, 2017

Version 53.0, first offered to Release channel users on April 19, 2017


Today's Firefox release makes Firefox faster and more stable with a separate process for graphics compositing (the Quantum Compositor). Compact themes and tabs save screen real estate, and the redesigned permissions notification improves usability. Learn more on the Mozilla Blog.

We'd also like to extend a special thank you to all of the new Mozillians who contributed to this release of Firefox!



new
  • Improved graphics stability for Windows users with the addition of compositor process separation (Quantum Compositor)

  • Two new 'compact' themes available in Firefox, dark and light, based on the Firefox Developer Edition theme

  • Lightweight themes are now applied in private browsing windows

  • Reader Mode now displays estimated reading time for the page

  • Windows 7+ users on 64-bit OS can select 32-bit or 64-bit versions in the stub installer
fixed
changed
  • Updated the design of site permission requests to make them harder to miss and easier to understand

  • Windows XP and Vista are no longer supported. XP and Vista users running Firefox 52 will continue to receive security updates on Firefox ESR 52.

  • 32-bit Mac OS X is no longer supported. 32-bit Mac OS X users can switch to Firefox ESR 52 to continue receiving security updates.

  • Updates for Mac OS X are smaller in size compared to updates for Firefox 52

  • The last few characters of shortened tab titles fade out instead of being replaced by ellipses to keep more of the title visible

  • Ended Firefox Linux support for processors older than Pentium 4 and AMD Opteron

  • New visual design for audio and video controls
pnamajck
it should be noted … a number of sandbox vulnerabilities have been addressed in this latest update (firefox-53.0) … thanks.

Mozilla has released Version 55.0 of the Firefox browser.

55.0
Firefox Release

August 8, 2017

Version 55.0, first offered to Release channel users on August 8, 2017


Today's release brings innovative functionality, improvements to core browser performance, and more proof that we’re committed to making Firefox better than ever. New features include support for WebVR, making Firefox the first Windows desktop browser to support VR experiences. Performance changes include significantly faster startup times when restoring lots of tabs and settings that let users take greater control of our new multi-process architecture. We’ve also upgraded the address bar to make finding what you want easier, with search suggestions and the integration of our one-click search feature, and safer, by prioritizing the secure - https - version of sites when possible. Read what Nick Nguyen (VP, Firefox Product) has to say about Firefox 55, get historical perspective on the development of WebVR from Sean White (SVP, Emerging Technologies) in this Medium post, and read about all the new features for developers in Firefox 55 on Mozilla Hacks.

We'd also like to extend a special thank you to all of the new Mozillians who contributed to this release of Firefox!



new
  • Launched Windows support for WebVR, bringing immersive experiences to the web. See examples and try working demos at Mozilla VR.

  • Added options that let users optimize recent performance improvements
    • Setting to enable Hardware VP9 acceleration on Windows 10 Anniversary Edition for better battery life and lower CPU usage while watching videos
    • Setting to modify the number of concurrent content processes for faster page loading and more responsive tab switching
  • Simplified installation process with a streamlined Windows stub installer
    • Firefox for Windows 64-bit is now installed by default on 64-bit systems with at least 2GB of RAM
    • Full installers with advanced installation options are still available
  • Improved address bar functionality
    • Search with any installed one-click search engine directly from the address bar
    • Search suggestions appear by default
    • When entering a hostname (like pinterest.com) in the URL bar, Firefox resolves to the secure version of the site (https://www.pinterest.com) instead of the insecure version (http://www.pinterest.com) when possible
  • Updated Sidebar for bookmarks, history, and synced tabs so it can appear at the right edge of the window as well as the left

  • Added support for stereo microphones with WebRTC

  • Simplified printing from Reader Mode

  • Updated Firefox for OSX and macOS to allow users to assign custom keyboard shortcuts to Firefox menu items via System Preferences

  • Browsing sessions with a high number of tabs are now restored in an instant

changed
  • Modernized application update UI to be less intrusive and more aligned with the rest of the browser. Only users who have not restarted their browser 8 days after downloading an update or users who opted out of automatic updates will see this change.

  • Firefox does not support downgrades, even though this may have worked in past versions. Users who install Firefox 55+ and later downgrade to an earlier version may experience issues with Firefox.

  • Made the Adobe Flash plugin click-to-activate by default and allowed only on http:// and https:// URL schemes. (This change will not be visible to all users immediately. For more information see the Firefox plugin roadmap)

Mozilla has released Version 57.0 of the Firefox browser, dubbed Firefox Quantum.

57.0
Firefox Release

November 14, 2017

Version 57.0, first offered to Release channel users on November 14, 2017


Brace yourself for an all-new Firefox. It’s fast. Really fast. It’s over twice as fast as Firefox from 6 months ago, built on a completely overhauled core engine with brand new technology from our advanced research group, and graced with a clean, modern interface. Today is the first of several releases we’re calling Firefox Quantum, all designed to get to the things you love and the stuff you need faster than ever before. Experience the difference on desktops running Windows, macOS, and Linux; on Android, speed improvements are landing as well, and both Android and iOS have a new look and feel. To learn more about Firefox Quantum, visit the Mozilla Blog.

Making Firefox look, feel and perform faster was no small feat. Employees and volunteers from around the world worked in record time to create the best Firefox yet. We'd like to extend a special thank you to all of the new Mozillians who contributed to this release of Firefox!

new
  • A completely new browsing engine, designed to take full advantage of the processing power in modern devices

  • A redesigned interface with a clean, modern appearance, consistent visual elements, and optimizations for touch screens

  • A unified address and search bar. New installs will see this unified bar. Learn how to add the stand-alone search bar to the toolbar

  • A revamped new tab page that includes top visited sites, recently visited pages, and recommendations from Pocket (in the US, Canada, and Germany)

  • An updated product tour to orient new and returning Firefox users

  • AMD VP9 hardware video decoder support for improved video playback with lower power consumption

  • An expanded section in preferences to manage all website permissions
fixed
changed
  • Firefox now exclusively supports extensions built using the WebExtension API, and unsupported legacy extensions will no longer work. Learn more about our efforts to improve the performance and security of extensions

  • The browser's autoscroll feature, as well as scrolling by keyboard input and touch-dragging of scrollbars, now use asynchronous scrolling. These scrolling methods are now similar to other input methods like mousewheel, and provide a smoother scrolling experience

  • The content process now has a stricter security sandbox that blocks filesystem reading and writing on Linux, similar to the protections for Windows and macOS that shipped in Firefox 56

  • Middle mouse paste in the content area no longer navigates to URLs by default on Unix systems

  • Removed the toolbar Share button. If you relied on this feature, you can install the Share Backported extension instead.

  • Some older versions of the ATOK IME, including ATOK 2006, 2008, 2009 and 2010, can cause crashes and are therefore disabled on the Windows 64-bit version of Firefox Quantum. To fix those incompatibility issues, please use a newer version of ATOK or one of other IMEs.

  • The default font for Japanese text is now Meiryo
developer
  • Complete visual refresh of both the Light and Dark DevTools themes, matching the new visual style of Firefox Quantum

  • The Inspector shows the values of CSS variables on hover

  • Completely new and re-designed Console panel. Joining the Debugger and the Network Monitor, the Console has been rewritten using modern web technologies such as React and Redux. It now also allows to inspect objects in context.
Developer Information
unresolved
  • Users running Firefox for Windows over a Remote Desktop Connection (RDP) may find that audio playback is disabled due to increased security restrictions. Learn how to mitigate this issue until it is corrected in an upcoming release

  • Users running screen readers may experience performance issues and are advised to use Firefox ESR until performance issues are resolved in an upcoming future release

  • On Windows and Linux, Firefox crashes occasionally on Intel Broadwell-U processors with old microcode. Windows users should ensure Windows Update is set to install updates. Linux users should ensure that the distribution package for Intel microcode is installed.
