how does jumpstart choose most visited?

[eichi]

i cant imagine, how jumpstart choose "most visited" links. If i
compare them with my history and visits, there are differences. its
half the same, but some pages are shown on a lower place, others a on
the front, i dont visited very often. can someone tell me more about
this?

hi,
I'm using frecency (should be the same thing Firefox uses for
navigation bar). It is not necessarily the same as the most frequently
used list, and unfortunately it can only be read directly from Places
database.

Here's a quote from Mozilla Developer Center (MDC):

Frecency is a score given to each unique URI in Places, encompassing
bookmarks, history and tags. This score is determined by the amount of
revisitation, the type of those visits, how recent they were, and
whether the URI was bookmarked or tagged.

Hope that answers your question. If you need more details let me know.
