Background
Firefox 3 introduced a number of improvements to the Location Bar. Among them were changes to how sites are ordered in the dropdown menu. Firefox takes into account how frequently and how recently sites in the browser history were visited, combining them into a statistic called “frecency.” The frecency of sites is calculated when the browser is idle. The way frecency is computed can be tweaked by a number of preferences.
When the browser needs to migrate history data from a pre-places version, it will calculate the frecency for a number of the imported visits to “prime the pump.” This preference determines how many of the imported entries to process during the migration.
Possible values and their effects
