This is my last day using firefox and anything mozilla
You turned off many of my extensions because they do not follow your new gawddamn rules is an outrageous abuse of power. How dare you!!
This was my last mozilla day. I am dumping all your products.
Go FUQ yourselves.
hi, this is/was caused by an unforseen 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/
