You set your history "kept" time in the menu options TOOLS -> OPTIIONS for both FireFox and M$ Internet Explorer. What ever you set it to, it keeps unless you run out of hard drive space. I am crazy and set mine to 365 days.
So, No. Unfortunately, there is no easy way to go back further than two months If yours is set to 2 months unless you want to go through hoops trying to recover deleted history files that are probably 'really' gone. (even though you jumped through hoops to try to get them back)
