It's all in the question, all of my 3rd party add ons via xpi files, were disabled and I have no idea how to re-enable them. I'm running on the beta, so that might be why it happened, but something like this is really shit of them to do, because I'm careful for my add ons and know which ones are installed, and they're add ons not featured in their addon page. So I'm really mad and pissed off now, so much so that if there isnt a fix, I'm just switching over to chrome
