After upgrading Firefox today to 66.0.3 in -current, all my add-ons were inactivated. A quick search showed that this is a widespread problem, apparently due to a bug in FF. I was able to fix it temporarily by means of a suggestion on ghacks.net to change
xpinstall.signatures.required in about.config to "false". Presumably it will be fixed soon upstream. -- Anthony Campbell http://www.acampbell.uk
