FirefoxMozilla sent Firefox Version 56.0 to the release channel today.  The update includes two (2) Critical, six (6) High, seven (7) Moderate and two (2) Low security updates.  Firefox ESR was updated to version 52.4.0.

Important Notes:  
  1. Although version 56 is scheduled to "silently and forcibly auto-upgrade" users running the 32-bit version of Firefox on 64-bit computers with more than 2GB of RAM to the 64-bit version, it was not updated to the 64-bit version on my machine. 
  2.  Users of Lenovo's "OneKey Theater" software for IdeaPad laptops and users running Firefox for Windows over a Remote Desktop Connection (RDP) are advised to check the unresolved issues below.
  3. Version 56 makes Firefox Screenshots and Send Tabs available to all users.
  4. See the following regarding add-ons starting in Firefox 57:  Firefox add-on technology is modernizing

    • Reorganized preferences so users can more easily scan settings
    • Rewrote descriptions so users can better understand choices and how they affect browsing
    • Revised data collection choices so they align with updated Privacy Notice and data collection strategy

Unresolved

  • Users running Firefox for Windows over a Remote Desktop Connection (RDP) may find that audio playback is disabled due to increased security restrictions. Learn how to mitigate this issue until it is corrected in an upcoming release
