I no longer have any:

passwords addons bookmarks history previously opened tabs user configuration

Nothing. Everything was completely wiped out. And that's just what I know about. Who knows what else is gone.

Does anyone know how I can retrieve this lost information.

Thank you.

If you lost personal data then it is possible that a new default-release profile folder has been created. See "Determine if Firefox has created a new profile":

You can open the about:profiles page via the location bar to check whether multiple profiles are present and what profile Firefox currently is using.

Firefox 67 and later can use a dedicated profile for each of the Firefox update channels and will lock the profile, so it can only be used by Firefox in a specific installation folder. For Release versions this profile would be a xxxxxxxx.default-release profile, profiles used in older Firefox versions usually used a xxxxxxxx.default profile (a refresh adds a time stamp).
