I'm also interested in why existing adds-ons are failing to run due to this problem. (There was a similar question in another thread about the issue here at HN.)
I understand why an add-on update or new installation would be prevented from succeeding by a certificate expiration. But why would a certificate expiration prevent an already-installed from running? Any already-installed add-ons were previously validated at installation time and should (IMO) run as-is. It seems unnecessary to continuously check the status of an add-on's certificate if it has not been changed. Am I missing something?
