How do I set how many months of history Firefox remembers? And how many months of history does Firefox normally remember?

It seems the ability to set the number of months (or weeks) for history data that will be remembered is absent from the history section of Firefox options. Is there a more indirect way to set how much History Firefox will remember, perhaps from about:config or so?

And secondarily, how much history *does* Firefox remember when I check "remember history"? I cannot find where that is specified. I assumed it remembered every site I've ever visited, but looking back in the "Older than 6 months" folder in History, I see that is not the case. There are only a few dozen sites there, while there should be hundreds (since I think I have never deleted History for about 2 years).

Chosen solution

Current Firefox versions keep a maximum number of visited page and 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 of this maximum as the value of the read-only pref places.history.expiration.transient_current_max_pages on the about:config page.

See Marco Bonardo's blog about this subject:

You can open the about:config page via the location/address bar. You can accept the warning and click "I'll be careful" to continue.
