Check to see if you have this folder on your computer:

c:\Users\<your username>\AppData\Roaming\Mozilla\Firefox\Profiles\<your profile>\bookmarkbackups\

If yes, just restore the latest of those backups.

That would only recover bookmarks.

You said there is no 'old Firefox' on your desktop? Please make sure.

Was this a regular update within Firefox Beta 57, or did this occur upgrading from Firefox Beta 56 to 57?

Have you restarted Windows since this problem occurred? Sometimes there are file lock/permissions issues that limit Firefox's access to its settings, so before struggling too long, I do recommend trying that.
