Doesn't work with FF55 Rated 2 out of 5 stars

I am trying to find a replacement for InformEnter that will work like InformEnter but will work with FF 57 when it is put out. I was hoping this would but I can not get it to fill in or I am just not understanding how....it should be easier so novices can put in info, right click and choose what you want filled it. Please make it simpler...like InformEnter.
