Firefox for Enterprise 78 - Release notes

Starting with Firefox 78, we will produce detailed release notes for issues that impact enterprises including bug fixes, enhancements, and policy changes.

Because this is our first enterprise release notes, we'll also be including notable changes between the last ESR (Firefox 68) and Firefox 78.

  • 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. Users can click a button on that page to view the site. If you want to allow TLS 1.0 and TLS 1.1, you can use the SSLVersionMin policy.
  • Support for reading client certificates from the operating system was introduced in Firefox 72 for Windows and 75 for MacOS and Linux. You can read more about it here. You can enable it by setting security.osclientcerts.autoload to true in the Preferences policy.
  • Starting with Firefox 75, Firefox will locally cache all trusted Web PKI Certificate Authority certificates known to Mozilla. This will improve HTTPS compatibility with misconfigured web servers and improve security.
  • With Firefox 77, You can view and manage web certificates more easily on the new about:certificate page.
  • Unlike the standard release of Firefox, user and enterprise added certificates are read from the operating system by default.
  • 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. You can read more about this here.

As previously announced in the Plugin Roadmap for Firefox, in Firefox 69 the Always Activate option for Flash plugin content has been removed. Firefox will now always ask for user permission before activating Flash content on a website. You can override this by adding domains in the FlashPlugin policy.

  • In Firefox 69, the Block Autoplay feature was enhanced to give users the option to block any video that automatically starts playing, not just those that automatically play with sound. This feature was also added to the Permissions->Autoplay policy.
  • Starting with Firefox 70, we show a gift box icon when there are new features in Firefox. This can be managed with the UserMessaging->WhatsNew policy.
  • In Firefox 71, the about:config page was reimplemented in HTML.
  • Picture-in-Picture support was introduced in Firefox 71 for Windows and 72 for MacOS and Linux. You can read more about it here. This can be managed with the new PictureInPicture policy.
  • Kiosk mode was introduced in Firefox 71. You can read more about it here.
  • Starting with Firefox 75, certain searches in the URL bar cause the user to receive Firefox specific suggestions. This can be managed with the UserMessaging->URLbarInterventions policy.
  • We now handle 407 from a HTTP/2 proxy. This was causing problems using the web version of WhatsApp. This was fixed in bug 1554218.
  • Add-ons that were blocked via policy could be installed via Sync. This was fixed in bug 1487529.
  • Even if permissions were locked by policy, they could still be updated by the user in the Page info dialog. This was fixed in bug 1630884.
  • Starting with 69, Firefox no longer loads userChrome.css or userContent.css by default. Users who wish to customize Firefox by using these files can set the toolkit.legacyUserProfileCustomizations.stylesheets preference to true to restore this ability.
  • Previously if you locked the homepage via the Homepage policy, the user couldn't choose Restore Previous Session option in preferences. We've separated locking the homepage from locking the start page by adding a new homepage-locked option for the Startpage. This was fixed in bug 1635825.
  • We made it easier to update add-ons that are installed via policy. If the add-on is installed from the local hard drive, it is updated any time the version changes. If it is installed from the web, it is updated anytime the filename changes. This was fixed in bug 1596481.
  • On Linux, you can put a policies.json file in /etc/firefox/policies and it will be used by all users on the system. This will override a policies.json file in the Firefox install directory.
  • A new Handlers policy has been added. This allows you to configure default application handlers for mime types, protocols and file extensions.
  • The DisabledCiphers policy has been updated. Previously setting a cipher value to true or false would always disable the cipher. Starting with Firefox 78, setting the value to true will disable the cipher and setting the value to false will enable the cipher. This allows you to enable ciphers that Firefox has disabled.
  • The ExtensionSettings policy has been updated to allow you to specify domains where you do not want add-ons to access the content.
  • Starting with Firefox 75, Firefox added a Default Browser Agent. This can be managed with the DisableDefaultBrowserAgent policy.
  • We've added a new PDFjs policy that allows you to turn on document permissions in the PDF viewer so users can't copy from secure documents.
  • Service Worker and Push APIs were disabled in all the previous ESRs, but are now enabled. Enterprise apps can utilize the offline support or push notifications in ESR. If your enterprise web application uses AppCache to provide offline support, you should migrate to these new APIs as soon as possible as AppCache will not be available in the next major ESR in 2021
  • Starting with Firefox 74, Add-ons installed by external applications can now be removed using the Add-ons Manager (about:addons). Going forward, only users can install add-ons; they cannot be installed by an application. This change is NOT in the Firefox 78 ESR.

Firefox Release Calendar

This schedule is based on the current RapidRelease plan. Future dates may change if the process changes. Code is not always released to users on the same day as the branch migration. The release to users may be a few days later, to allow for manual testing and sign-off. Thunderbird tracks the ESR schedule column per Thunderbird release info.

Calendars

This wiki page may not always have the most current information. Please refer to one of the following calendars for up-to-date scheduling:

Version 78.0, first offered to Release channel users on June 30, 2020

Firefox 78 is the last major release with support for macOS versions 10.9, 10.10 and 10.11. If you use one of these versions, you’ll be supported through Firefox ESR (Extended Support Release) 78.x for the coming year.

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

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

  • 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.

  • 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.
