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.

See Marco Bonardo's blog about this:
