The bug report and discussion is here: https://bugzilla.mozilla.org/show_bug.cgi?id=1548973 This is supposed to have updates but I think that the server is being swamped by people checking and the page doesn't work: https://discourse.mozilla.org/t/certificate-issue-causing-add-ons-to-be-disabled-or-fail-to-install/39047 As of 12 minutes ago the status is 'we are making progress'. -- You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.
