And I suspect that if you had a virus scanner installed on windows every file it scanned would be logged somewhere depending on settings.

This post also fails to mention that this is specific to Safari at last check. I don't think Google Chrome integrates with this functionality.

Chrome does integrate with this functionality.

Also, some apps doesn't even need to integrate, as the OS will override and auto-apply files for some blacklisted apps, see /System/Library/CoreServices/CoreTypes.bundle/Contents/Resources/Exceptions.plist for LSFileQuarantineEnabled

It does now:

    $ sqlite3 ~/Library/Preferences/com.apple.LaunchServices.QuarantineEventsV* 'select LSQuarantineAgentName from LSQuarantineEvent'|grep 'Google Chrome'|wc -l
          35

But firefox doesn't seem to be in the list, though I am using the Firefox Nightly so that has something to do with it. I have Adium (lot of sparkle update checks), Chrome (just used for testing), iChat and a couple other random one-offs.

Firefox seems to be "blacklisted" by Apple, see /System/Library/CoreServices/CoreTypes.bundle/Contents/Resources/Exceptions.plist :

                <key>org.mozilla.firefox</key>
                <dict>
                        <key>LSFileQuarantineEnabled</key>
                        <true/>

Nightly is org.mozilla.nightly, so that explains the grandparent's behaviour differing, since the Apple blacklist does not include it.

I don't use Safari and it has all my downloads from Google Chrome.

I use a safari/firefox mix, all that's in that db for me is a short list of things I don't care about...
