IIRC the problem isn't that people are running 32-bit Firefox it is that
certain plugins only have 32-bit versions. So e.g. a 64-bit OS X 10.10 is
still running a 32-bit plugin process for certain plugins.

I think the data we need is how many users are running 32-bit NPAPI
processes on OS X > 10.8 (only the 10.9+ population is relevant because
we've dropped 10.6-10.8). Then we can have a conversation about dropping
32-bit NPAPI on OS X before 53.
