Yes, you can. I succesfully updated 0.9.2 to 0.9.3 using that methode lately. You can even delete the whole Firefox folder afterwards, because settings are stored in a diffrend folder. C:\Documents and Settings\username\Application Data\Mozilla to be exactly. It might store some things in C:\Documents and Settings\username\Application Data\Phoenix too, but i'm not sure, but i have that folder on my harddisk anyway. Back these folders up to make absolutely sure nothing can go wrong.
