Yes. The file contains a cookie permission for openstreetmap.org.

Yes. Since Firefox 17, we consider "scheme:file" as an invalid entry. Basically, the cookie permissions in the file are the following:
schafmail.de
scheme:file
openstreetmap.org

Firefox 16 reads, accepts and loads all of them (thus, three of them listed).
Firefox 17.0.0 accepts "schafmail.de" but refuses "scheme:file" so stop reading the permissions, thus do not load "openstreetmap.org"
Firefox 17.0.1 also refuses "scheme:file" but continue to read the file so "openstreetmap.org" is loaded.

The behaviour you see seem fine to me.
