If in doubt, don’t. Hardening, whether applying to film or paper is a solution which has a tanning effect on gelatin, limiting the subsequent uptake of water and making the material less liable to mechanical damage.

This can be necessary when for example, heat drying glossy FB prints, or processing film in tropical conditions. It is not usually necessary in room temperature operations in the UK, and will make fixing significantly less efficient.
