Hi azazure, Firefox stores bookmarks together with history in a database (the Places database) together with all your other critical Firefox data in your "profile" folder. It is possible to set Firefox to look for your profile folder on a different drive, but it is not to put only bookmarks (or only the Places database) on a different drive, outside of your profile folder. Does a profile move sound like it's worth pursuing, or did you have a more limited objective in mind??

Ref. Profiles - Where Firefox stores your bookmarks, passwords and other user data

On Windows you can create symbolic links, but I do not know whether this works properly with respect to places.sqlite-shm and places.sqlite-wal SQLite temp files.
