#There is no longer a user-settable time limit setting in Firefox 4 and newer versions for History.

If you keep losing older history then see if you have cleanup software running that removes that history on a scheduled base.

Unfortunately or not, I upgraded a while back to v 9.0, so I suppose I'm stuck with the automatic feature. (Ideally, I would like to save 12 months plus current month.) If I increase my cache space, will more history be saved? If not, is there any way to export or save history?

Naw, thanks, but already thought of that.
