Seems good so far Rated 4 out of 5 stars

Nice little utility; the reviewer who complains about it (and all other wipe utilities) not wiping ATA drives or whatever has a specious argument. Windows itself is not very private and poses more threats to security than anything else. And as far as the 3-pass DOD spec wiping algorithm, it's good enough. I don't want to sit there waiting for a 35-pass Gutmann wipe. If you're an international spy and are trying to hide information that would start World War III or something, then yeah this might not be secure enough for you. But for 99.99% of other people this will be good enough. If "Recuva" can't find it, then that's good enough for me.

I'm assuming from the author's post about FF 3.5+ not wiping on application close means that you need to add it to the toolbar and manually wipe when you need to. I don't want to install a util that asks me whether I want to wipe every single time I close FF, because 99 times out of 100 I don't need to wipe anything. But manually is fine too, if a little bit cumbersome.
