Release Note For Firefox 78 Update!

  • 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.


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


  • 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.
  • Firefox 78 is the last major release with support for macOS versions 10.9, 10.10 and 10.11. Users of these macOS versions will be supported through Firefox ESR 78.x for the coming year.
  • 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.


  • 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.
  • Enable support for client certificates stored on macOS and Windows by setting the experimental preference security.osclientcerts.autoload to true.


  • Developer Information
  • 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.
