hi Joy55, this is/was caused by an unforeseen technical problem unfortunately (an expired certificate used in the process of verifying addon signatures).

a fix for this is already being rolled out - for details, please see: https://blog.mozilla.org/addons/2019/05/04/update-regarding-add-ons-in-firefox/
