Welcome - I'm somewhat new here myself, but I am working on IndexedDB
support in WebKit..

What do you mean by "tracker" ?

tends to deal with stuff at a slightly lower level (i.e. actual paths on
disk, etc) - are you looking for a url path? All the IDB's for a security
origin are accessable to each other, and not connected to the rest of the
URL (i.e. http://foo.com/abc has the same security origin as
http://foo.com/xyz so they have access to the same set of IDB files, so
indexedDBDatabasePath() is the same)
