Book marks and library does not work

Bookmarks and library does not work for Firefox or Waterfox. For some reason The bookmarks don’t function, nor can I recover old bookmark files. I open the Bookmark Library and it is empty, I try to recover an old Bookmark file and it responds with recovery not completed. So what happened? how do I fix the problem?

This sounds like a general Firefox issue, which is probably solved better at the support forum:

Thanks, I’ll look into that.
