Why have my addons become legacy addons and cannot be used?
they worked perfectly fine and the next day they didnt, please help me fix this! D: im using firefox 66.0.3 (64 bit)
the addons that stopped working are adblock plus, ghostery, dark mode, and another adblock
Chosen solution
hi w00tnoway, 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: Add-ons disabled or fail to install on Firefox
