How do I restore bookmarks

Restored my pc and lost all bookmarks. How do I get them back? If you had Firefox Sync enabled, sign in to the same Mozilla account and check that Bookmarks syncing is turned on. Otherwise, check whether your old Firefox profile or a Windows backup still exists. You can open about:profiles in Firefox to look for another profile. If you find an old profile, your bookmarks may still be there. Unfortunately, if the profile was erased and there’s no backup or Sync copy, they may not be recoverable.
