Background
Mozilla keeps no more than a set number of entries in its browsing history. This helps performance by reducing the amount of information that must be kept in memory while the browser is running. This preference determined the maximum number of history entries the browser kept. It has since been renamed to browser.history_expire_sites, which behaves slightly differently.
Possible values and their effects
A positive integer, specifying the maximum number of history entries (“visits”) the browser should keep when expiring old entries. Default value is 20000.
Caveats
- Even if there are fewer history entries than this preference specifies, history entries may expire based on their age, per browser.history_expire_days.
