68.0 Firefox Release

July 9, 2019

Version 68.0, first offered to Release channel users on July 9, 2019

Today, we release two versions of Firefox 68 — a rapid release as well as an Extended Support Release (ESR).

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


  • Dark mode in reader view expands so that windows are also dark on the controls, sidebars and toolbars.

  • Improved extension security and discovery:

    • New reporting feature in about:addons allows you to report security and performance issues with extensions and themes.
    • Redesigned extensions dashboard in about:addons provides easy access to information about your extensions, including data and settings access required by each extension.
    • Find high quality, secure extensions via the Recommended Extensions program in about:addons, which now displays user count and ratings for each extension. "Recommended” badges for these extensions also appear on AMO. More extensions will be added over time.
  • Cryptomining and fingerprinting protections are added to strict content blocking settings in Privacy & Security preferences.

  • WebRender will roll out to Windows 10 users with AMD graphics cards.

  • Windows Background Intelligent Transfer Service (BITS) update download support, which allows Firefox update downloads to continue when Firefox is closed.


  • Various security fixes

  • Local files can no longer access other files in the same directory.


  • Unified existing locales (bn-BD, bn-IN) under a single Bengali (bn) localization.

  • The following unmaintained translations have been removed: Assamese (as), English - South Africa (en-ZA), Maithili (mai), Malayalam (ml), Odia (or). Existing users will be migrated to the British English (en-GB) version.

  • When an HTTPS error caused by antivirus software is detected, Firefox will attempt to automatically fix it

  • Camera and microphone access now require an HTTPS connection.

  • The way non-default preferences are synced has changed. Please see this support article for more details


  • For all operating systems, we have a number of additional policies including:

    • New tab page configuration and disabling
    • Local file links
    • Download behavior
    • Search suggestions
    • Managed storage for using policies in Webextensions
    • Extension whitelisting and blacklisting by ID and website
    • A subset of commonly used Firefox preferences

    You can see a full list of policies here.


  • Firefox Developer Tools now offers a full page color contrast audit that identifies all elements on a page that fail color contrast checks.

  • Added about:compat, where website-specific workarounds are listed and may be toggled. These workarounds are meant as temporary fixes for various forms of website breakage for Firefox, while the website fixes them in due time. With about:compat, it is now easy to see all of the workarounds that are active in Firefox, and easy for website developers to disable a given workaround for testing purposes.

  • Introduces CSS Scroll Snap module that enforces scroll snap positions.


  • The new URL bar implementation does not handle javascript: bookmarklets triggered via bookmark keywords correctly yet (bug 1552141)

  • Windows administrator users with UAC turned off may no longer be able to drag content out of Firefox. See this support article to learn more
