FFF - FireFoxFuctions - some download related functions for FireFox since original FF.au3 still lack them.
Names of functions is pretty clear:
_FF_AddDownload_DM --> Add new download to Firefox download manager using nsIDownloadManager (This interface is deprecated as of Firefox 26)
_FF_AddDownload_TR --> Add new download to Firefox using nsITransfer (should work in any FF 10+)
_FF_GetDownloadState_List --> Return number or list of States of all
