Yet Mozilla blocked my installation of TidyRead as unsigned, even though the source was https://addons.mozilla.org/.Mozilla verifies and "signs" add-ons that follow a set of security guidelines. All add-ons hosted on addons.mozilla.org undergo this process in order to be signed.
There's obviously an error someplace. Was the error to list TidyRead or to block it? How if at all could I follow up?
