hi pilan89, this is/was caused by an unforeseen technical problem unfortunately (an expired certificate used in the process of verifying addon signatures).

mozilla just released the official update to v66.0.4 which should mitigate this problem. you can manually trigger it by going to the firefox menu ≡ > help > about firefox panel.

for more details, please see: Add-ons disabled or fail to install on Firefox
