Restarting Windows XP PC, Firefox Sessions restore old Session, not the latest one I closed Firefox on.

I formatted my PC, and re-installed Firefox I backed up application data regarding firefox settings, after re-installing everything on pc and installing firefox I can see my old tabs from last session but when i say delete them and or make new tabs and the option in Tools still states Show my windows and tabs from last time, I then reboot my pc and when firefox loads up again the session is loaded from an old session before the format, I create new sessions and Firefox saves them when i close and open them but every time i reboot my pc it always loads the pre-format sessions. How Can i make firefox normal again without wiping my application data, passwords and settings and re-installing the program? There must be a way.

You can check for problems with the sessionstore.js and sessionstore.bak files in the Firefox Profile Folder that store session data.

Delete the sessionstore.js file and possible sessionstore-##.js files with a number and sessionstore.bak in the Firefox Profile Folder.

Deleting sessionstore.js will cause App Tabs and Tab Groups and open and closed (undo) tabs to get lost, so you will have to create them again (make a note or bookmark them).
