Mozilla Firefox Version 66.0.4 Released To Replace Expired Certificate

[Corrine]

Mozilla sent Firefox Version 66.0.4 to the release channel today to replace the expired certificate that resulted in add-ons being disabled. Note, however, that there are a number of unresolved issues, listed below.  Firefox ESR was updated to Version 60.6.2.

Fixed

• Repaired certificate chain to re-enable web extensions that had been disabled

Unresolved

• A small number of add-ons may be listed as unsupported or may not appear in about:addons. Their data is not lost; users should be able to re-install the add-ons and recover the data (Bug 1549129). More support information
  
• If add-ons that use Containers functionality (such as Multi-Account Containers and Facebook Container) were disabled as part of this problem, any lost site data or custom configurations for those add-ons will not be recovered by this release. Users may need to set them up and login again in about:addons (Bug 1549204). More support information
  
• Themes may not be re-enabled. Users may need to re-enable them in about:addons (Bug 1549022). More support information
  
• Home page or search settings customized by an add-on may be reset to defaults. Users may need to customize them again in about:preferences or about:addons (Bug 1549192). More support information

Update: To get the update now, select "Help" from the Firefox menu, then pick "About Firefox." Mac users need to select "About Firefox" from the Firefox menu. If you do not use the English language version, Fully Localized Versions are available for download.
