Make sure the mentioned options are set to enabled to get it fixed!!

If you are still curious install the Hotfix manually from this link and all disabled add-ons etc are re-enabled once again.

Installing or upgrading to v 66.0.4 fixes the issue. Also make sure you upgrade the extensions after doing the ff upgrade.

Mozilla is lazy and careless but can't seem to stop whining about Google's increasing Monopoly in the market. They broke their entire Add on system by centralizing the Add on code signing process and then can't be bothered to keep the certs used in the code signing process updated when they expire. Think this already happened once some years ago and we see it happen again. They should be rightfully embarrassed about this.
