Not exactly the answer to your question, but an alternative to the logistf package, which purports to do similar things, is brlr (which does provide a predict method). Does this work for you?

   library(brlr)
   data(sex2)
   fit <- brlr(case ~ age + oc + vic + vicl + vis + dia, data = sex2)    predict(fit, newdata = sex2)
