Shame it doesn't allow you to merge the imported bookmarks with the current bookmarks you now have, as unfortunately it wipes out any more recent bookmarks you may have added since the backup was made.
You can merge bookmarks, by going into Bookmarks Manager (CTRL+Shift+O) then go to Import and Backup, then Export the bookmarks To HTML Save them on a USB Stick, then go to the machine you want to merge them with, plug the usb in go into Bookmarks Manager and then Import and Backup then Import Bookmarks From HTML and then select the file you exported onto your USB and your bookmarks will be merged!
