Firefox disabled 2 add-ons I didn't install. They were part of a web game called Achae I was playing that is Nexus based. Thus I have no way to re-install them. I download Nightly and turned off signatures but that didn't help. Apparently that doesn't restore your add-ons, just allows you to re-install them. I'm trying to get help through the game but they don't know how to help me.
I'm very upset because I really like this game and without my permission Firefox just killed it. Security is one thing, but I should have some say-so in the matter.
