Hi scherryd, there is a general problem with most add-ons at the moment. A critical certificate Firefox uses to verify their digital signatures has expired, and you need a new one to resume using the affected extensions.

Please see this article for more information: Add-ons disabled or fail to install on Firefox.

Also, Firefox 66.0.4 is expected later today with a fix if the interim hotfix hasn't come through.

Firefox 66.0.4 was just released for both desktop Firefox and Android Firefox, which should fix the expired certificate problem. An updated Firefox 60 ESR (60.6.2esr) was also released.

• Desktop: Update Firefox to the latest release
• Android: Probably in Google Play?

Sometimes the auto-updater doesn't see an update right away, either because it isn't scheduled to check yet or when you click Check for Updates, because the server is limiting the rate of installations "just in case" it creates a new problem.

At some point, we should get the 66.0.4 and 60.6.2esr full installers through the usual pages, but I currently get the older version:

• Regular release: https://www.mozilla.org/firefox/all/
• ESR release: https://www.mozilla.org/firefox/organizations/all/
