I'm trying to find out what sites I was on one year ago but the history only keeps track up to 6 months. Is there any way to retrieve history from a year ago?

No, if history is only kept for 6 ,months then older history is no longer available.
The default in Firefox 3 versions is to keep history for 180 days (6 months).

In Firefox 4+ that has changed to a maximum number of pages that is kept.
So you can update to Firefox 8 and it will remember more history, but you can't get back older history.

There is no time limit in Firefox 4+ versions for the history.
Firefox determines automatically how many pages can be kept without affecting the performance.
You can see the current value via the reads-only pref places.history.expiration.transient_max_pages on the about:config page.
