I had to reset Firefox. But I lost all my fireform data. How do I retrieve that data from the Old Firefox Data folder? It's in the about:config file.

Also, when I start Firefox my previous session is always restored even though my options say to start a new page. How do I fix this without resetting Firefox?

You can check if you have an user.js file in the Firefox profile folder that sets the browser.sessionstore.resume_session_once pref to true.

You can check the content of the prefs.js file with a text editor to see if you can locate that data and copy the related line(s) to the prefs.js file of the current Firefox profile folder.
