Your minimal "suggestion" was unhelpful. Obviously, I had visited the site
and found that much on my own. Don't work too hard and thanks for nothing.
Not quite clear what your question is...
Do you need to know if you should install the 32-bit or 64-bit version? If it's for the 32-bit Firefox, then you should install the 32-bit version.
Or do you want to know which of the installers you should use?
