-firthlogit- is a user written program, please specify 
how and where you got that program. This is in your own 
interest: often there are multiple versions of floating
around in cyber space: if you don't tell us what version
you are using, we obviously cannot help you.

I will assume that you are using the program by Joseph 
Coveney, and that you downloaded it from SSC by typing in 
Stata -ssc install firthlogit-.

R2 and adjusted R2 are statistics of fit that follow logically
from the framework of linear regression. They do not follow
as logically from other models, which is why there are so
many "pseudo"-R2 measures out there. A do-it-yourself guide
for one of these pseudo measures can be found here:

Hope this helps,
