That is a JSON backup and needs to be restored.

  • Bookmarks > Show All Bookmarks > Import & Backup > Restore > Choose File

Note that restoring a JSON backup will replace all your current bookmarks (you get a warning about that).
If you already have bookmarks that you wish to keep then export them to an HTML file before restoring the JSON backup.
You can import that HTML file after you have restored the JSON backup to get your current bookmarks back (you need to remove duplicates).
You can't import a JSON backup to add (merge) bookmarks.
