Disable or delete places.sqlite

Xulrunner automatically creates a places.sqlite file in the profile directory. Due to performanve optimizations it is at least 10MB of size and grows in chunks of 10MB. Is there a way to disable the history to get rid of this file or at least delete it on application closing? My problem is that the profile of the users of my xulrunner application is stored on a server and so the profile gets very large.

I searched a bit around but didn't find a way to solve my problem.
