80.0

New

  • 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:

  • 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.
79.0

New

  • We’ve rolled out WebRender to more Windows users with Intel and AMD GPUs, bringing improved graphics performance to an even larger audience.
  • Firefox users in Germany will now see more Pocket recommendations in their new tab featuring some of the best stories on the web.

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.

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 79 Release Notes.
  • Updates to the password policy allow admins to require a primary password (formerly called master password.
    Previously the policy could disable the primary password but not force a primary password.
    Users required to use a primary password will only be asked to create a primary password the first time they try to save a password.

Developer

  • Newly added asynchronous call stacks let developers trace their async code through events, timeouts, and promises.
    The async execution chains are shown in the Debugger’s call stack, but also for stack traces in Console errors and Network initiators.
  • Erroneous network responses with 4xx/5xx status codes display as errors in the Console, making it easy to understand them in the context of related logs.
    The request/response details can be expanded or resent for quick debugging.
  • JavaScript errors are now visible not only in the Console, but also in the Debugger.
    The relevant line of code will be highlighted and display error details on hover.
  • Opening SCSS and CSS-in-JS sources from the Inspector now works more reliably thanks to improved source map handling across all panels.

78.0

New

  • The Protections Dashboard includes consolidated reports about tracking protection, data breaches, and password management. New features let you:
    Track how many breaches you’ve resolved right from the dashboard
    See if any of your saved passwords may have been exposed in a data breach
    To view your dashboard, type about:protections into the address bar, or select “Protections Dashboard” from the main menu.
  • Because we know people try to fix problems by reinstalling Firefox when a simple refresh is more likely to solve the issue, we’ve added a Refresh button to the Uninstaller.
  • With this release, your screen saver will no longer interrupt WebRTC calls on Firefox, making conference and video calling in Firefox better.
  • We’ve rolled out WebRender to Windows users with Intel GPUs, bringing improved graphics performance to an even larger audience.
Firefox 78 is also our Extended Support Release (ESR), where the changes made over the course of the previous 10 releases will now roll out to our ESR users. Some of the highlights are:
  • Kiosk mode
  • Client certificates
  • Service Worker and Push APIs are now enabled
  • The Block Autoplay feature is enabled
  • Picture-in-picture support
  • View and manage web certificates in about:certificate
  • Pocket recommendations, featuring some of the best stories on the web, will now appear on the Firefox new tab for 100% of our users in the UK.
    If you don’t see them, you can turn on Pocket articles in your new tab, follow these steps.

Fixed

  • Various security fixes.
  • We fixed bugs in the search results quality composition and improved search result texts based on recommendations by our partners.

Changed:

  • The minimal system requirements on Linux have been updated.
    Firefox now needs GNU libc 2.17, libstdc++ 4.8.1 and GTK+ 3.14 or newer versions.
  • As part of our ongoing effort to deprecate obsolete cryptography, we have disabled all remaining DHE-based TLS ciphersuites by default.
    To mitigate web compatibility issues from disabling DHE-based TLS ciphersuites, Firefox 78 enables two more AES-GCM SHA2-based ciphersuites.
  • We have disabled TLS 1.0 and TLS 1.1 to improve your website connections.
    Sites that don't support TLS version 1.2 will now show an error page.
  • The context menu (accessed by right clicking on a tab) lets you undo multiple tab closings with a single click and places Close Tabs to the Right and Close Other Tabs in a submenu.
  • A number of accessibility improvements have been made with this release.
    When using the JAWS screen reader, pressing the down arrow in an HTML input control with a datalist no longer incorrectly moves the cursor to the next element after the input control.
    Screen readers no longer severely lag or freeze when focusing the microphone/camera/screen sharing indicator.
    Large tables with thousands of rows now load much faster for screen reader users.
    Text input controls with custom styling now correctly show the focus outline when appropriate.
    Screen readers no longer sometimes incorrectly switch to document browsing mode unexpectedly when the user enters the main Developer Tools window.
    We reduced a number of animations such as tab hover, search bar expansion, and others to reduce motion for users with migraines and epilepsy.

Enterprise

  • Enable support for client certificates stored on macOS and Windows by setting the experimental preference security.osclientcerts.autoload to true.
  • New policies allow you to configure application handlers, disable picture in picture, and require a master password, which will be renamed to ‘primary password’ in future releases.
  • More details in the Firefox for Enterprise 78 release notes

Developer

  • DevTools Console now logs uncaught promise errors with much more detailed names, stacks, and properties, particularly improving JavaScript framework debugging.
  • Debugger’s automatic mapping for minified variable names now also works for Logpoints, which makes debugger of source-mapped projects feel more seamless.
  • The Firefox DevTools’ Network panel now highlights which extension or CORS restriction blocked a request, so developers can make their sites more resilient and secure.
  • New RegExp engine in SpiderMonkey, adding support for the dotAll flag, Unicode escape sequences, lookbehind references, and named captures.
77.0.1

Fixed

  • Disabled automatic selection of DNS over HTTPS providers during a test to enable wider deployment in a more controlled way
77.0

New

  • Pocket recommendations, featuring some of the best stories on the web, will appear on the Firefox new tab for our users in the UK. If you don’t see them, you can turn on Pocket articles in your new tab, follow these steps.
  • WebRender continues its roll out to more Firefox for Windows users, now available by default on Windows 10 laptops running on Nvidia GPUs with medium (<= 3440x1440) and large screens (> 3440x1440).
  • You can view and manage web certificates more easily on the new about:certificate page.

Fixed

  • Various security fixes.

  • The browser.urlbar.oneOffSearches preference has been removed.
    To hide one-off search buttons uncheck search engines on the about:preferences#search page

Developer

  • Significant improvements to JavaScript debugging make loading and stepping through sources faster and with less memory being used over time.
    Source map support also got a lot more reliable and will just work for a lot more cases.
  • Added support for the JavaScript API String.prototype.replaceAll() which allows developers to return a new string with all matches to the provided pattern while preserving the original string.
