I don't see this as really being a question for StackOverflow, but I will answer it anyway.
I think the writing on the wall is clear: NPAPI plugins are going away. This seems extraordinarily shortsighted to me, since those who have made this decision have not given us any solutions that can solve most of the problems currently solved with FireBreath. Some of those problems I don't believe there is any reasonable solution to; others there are a few possibilities, but we need to brainstorm solutions.
Over the next few weeks (and possibly more) we will be discussing possibilities and, assuming the community is willing to help, we will build a solution that will address as much of the gap as is possible.
I am not yet prepared to speculate in this public of a place on what that will look like, but we do have some ideas.
