Hi @wolflover2305, We understand your problem. This has been caused by a certificate issue. Firefox Team is currently working on a fix and will be providing updates on this thread: [[FIXED] Certificate issue causing add-ons to be disabled or fail to install](http://discourse.mozilla.org/t/certificate-issue-causing-add-ons-to-be-disabled-or-fail-to-install/39047) 🙂
