 1. Run TBB v3.5.3
 2. Click on a link to download an archive or any file type not natively
 handled by the browser
 3. Wait for the download to complete
 4. Observe that <random>.ext.part file is created containing entire file
 contents in the system's %temp% folder.
 4. In the Open/Save dialog box click Cancel.
 5. Observe that the temp-created file is not removed.
 6. Close Firefox/TBB.
 7. Observe that the temp-created file is not removed.

 Firefox 28's Private Mode does not have this bug.
 I observed this bug in TBB v2.x as well.
