Firefox v66.0.4 releases to repaired certificate chain

by · Published · Updated

Mozilla Firefox 66.0.4 has been released and contains a fix for an expired intermediate signing certificate that caused everyone’s plugin to be disabled a few days ago.
To use this fix, users need to enable Studies. However, this option by default provides Mozilla with information about how users use Firefox, and many people are concerned about the privacy risks.

However, even if Studies is enabled, some users report that they have not received the fix.

Firefox 66.0.4 is now finally released, including a new intermediate signing certificate that has not expired, and will force a revalidation of the signature.

The problem of plugin invalidation has been basically fixed, but the announcement of 66.04 indicates that there are still some minor issues to be resolved:
  • 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
