The only thing I could suggest, if you can't use the "Last known Good" option on the recovery system, is to boot into something offline and change the name of the file, to a .bak or something instead of .sys.
The Safe Mode boot normally shows ClassPnP as the last file while loading, so showing the other one may mean it is causing the problem, but I can't say for sure the one after it is not involved. You would probably need a bootlog to tell for sure.
Edit: It also appears in your Users\AppData\Roaming\Mozilla\Firefox\Profiles\Somestrangename folder, there is a Bookmarksbackups folder. Maybe you can use that to move the bookmarks. AppData is a hidden folder so you need to set it viewable in the folder options, view options...
