| 10 * Expiration will obey to hardware spec, but user can set a custom maximum | |
| 11 * number of pages to retain, to restrict history, through | |
| 12 * "places.history.expiration.max_pages". | |
| 13 * This limit is used at next expiration run. | |
| 14 * If the pref is set to a number < 0 we will use the default value. | |
