Mozilla Firefox 68 Beta 12 (Quantum)今日發布，新版帶來了擴展的安全升級，面向AMD圖形卡的Windows 10桌面上也開始默認啟用WebRender，新版還啟用了預加載中間TLS證書的能力，這可以避免在服務器配置錯誤的情況下出現錯誤頁面，並在渲染時對BT601，BT709和BT2020 / 2100色彩空間提供了支持。

New

• 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.
• When an HTTPS error caused by antivirus software is detected, Firefox will attempt to automatically fix it
• New reporting feature in about:addons allows you to easily report security and performance issues with extensions and themes
• Find high quality, secure extensions via the Recommended Extensions program. Look for these vetted extensions in about:addons
• WebRender is being enabled on Windows 10 desktops with AMD graphics
• Access your Firefox Account settings from the hamburger menu
• Added a Firefox shortcut in the Windows 10 taskbar for new installations
• Preloading of intermediate TLS certificates is enabled in early beta builds, which avoids error pages in cases of server misconfiguration
• Properly support BT601, BT709 and BT2020/2100 colorspaces on all platforms
• In addition to providing color contrast information for individual elements of a page, Firefox now offers a full page color contrast audit that identifies all element on a page that fail color contrast checks.

Changed

• Unified existing locales (bn-BD, bn-IN) under a single Bengali (bn) localization.
• Removed unmaintained languages: Assamese (as), English – South Africa (en-ZA), Maithili (mai), Malayalam (ml), Odia (or). Existing users are migrated to the British English (en-GB) version of Firefox .
• The AwesomeBar has been rewritten using Web Technologies only (HTML, JS and CSS). Differences include that results that overflow now have a nice fading effect instead of an ellipsis, and removing history items from the results now requires a different key combination on both Windows and Linux: Shift+DEL or Shift+Backspace
