* clearHistory (bool, optional):
* Whether or not to simulate clearing session history.
* Defaults to false.
*
* setDir (nsIFile, optional):
* An nsIFile for setting the last download directory.
* If not set, the load download directory is not changed.

* expectedDir (nsIFile, expectedDir):
* An nsIFile for what we expect the last download directory
* should be. The nsIFile is not compared directly - only
* paths are compared. If expectedDir is not set, then the
