Mozilla Releases Fix for Firefox Add-On Snafu

Mozilla drew the fury of Firefox users Friday when the browser company accidentally allowed a certificate to expire, preventing add-ons from working or being installed throughout the weekend. An official fix was released Sunday in the form of version 66.0.4, which should restore that crucial functionality.

A Firefox release has been pushed — version 66.0.4 on Desktop and Android, and version 60.6.2 for ESR. This release repairs the certificate chain to re-enable web extensions, themes, search engines, and language packs that had been disabled (Bug 1549061). There are remaining issues that we are actively working to resolve, but we wanted to get this fix out before Monday to lessen the impact of disabled add-ons before the start of the week.
