Firefox Cookies/history/cache Accidently Deleted- Is there ANY way to retrieve or restore them????

I haven 't cleared or deleted my firefox cookies or history in about 2 years! Now everything is gone

Immediately after, I tried doing a system restore but that did not work. The cookies, history, and everything are still missing.
I've checked google for some solutions but to no avail.
Some perhaps useful information: I'm using firefox 3.6.17 on windows xp.
Does anyone have a solution for how I can retrieve my firefox cookies???
*additional info*
I'm pretty sure the cookies are what I'm referring to but maybe its not.
You know when you use firefox and you type in a few letters in the address bar and firefox will give you suggestions of websites that you've previously visited that match the actual site or title (even if its months old). This is what has gone and what I want to recover. Is cookies the correct term? Or perhaps they are called cache files?
