Why does my history stores so little?
Firefox stores only 1-month old history. Why? Can i configure the time of storing? And Download History stores so little. (But i think it problem because Download StatusBar addition)
You may have cleanup software running on your computer if older history gets removed.
With build-in Firefox means you can only remove recent history and not older history unless you do this manually in the History Manager (Library)
- History > Show All History
Firefox 4+ versions do not have a time limit for the history.
Firefox determines automatically how many pages can be kept without affecting the performance.
You can see the current value via the read-only pref places.history.expiration.transient_max_pages on the about:config page.
