I cannot understand how to use your app -- it seems that i continually get the message about making RetailMeNot an ADD-ONs to my Firefox Browser. I try to Add it and then when I login in and try to use your Deal Finder app -- it just continually sends me through the steps again and again of making RetailMeNot and ADD-ON to my Firefox. Okay, I have added it -- now how do i use it? Not clear to me. Please please dumb down your instructions.
