Unless things have changed, Im pretty certain Microsoft doesnt use posix or "unix" time...

Windows NT time is specified as the number of 100 nanosecond intervals since January 1, 1601. UNIX time is specified as the number of seconds since January 1, 1970. There are 134,774 days (or 11,644,473,600 seconds) between these dates.

Maybe things have changed since NT... but Id have my doubts.

Not that that changes your point. It doesnt. Just sayin.

If you set the value of this to "2", you will get what you're looking for. Sort of... This will cause Firefox's "awesome" bar to match "LIKE 'foo%'". However, it will still look at page titles, not strictly URL. Still, this is the closest Ive been able to come to replicating old behavior.
