'''I'm on Mac and I had restarted Firefox and suddenly I had a new bar under my tabs. When I right clicked on it there were options like Apps Gallery, etc and they seemed to lead apps.conduit.com. I hadn't approved or installed such a feature so I wanted to remove it but there was no such option. After some search, I realized many people had the same problem. They were told to remove it from Tools->Add-ons but it's not on my add-ons list!! I want to remove this "Conduit engine" thing, please help me. Thanks in advance!'''
