I need to restore my bookmarks from November, which I see when I hit 'Show All Bookmarks -> Import and Backup'. But it only wants to restore them to this computer, which will over-write all of my existing bookmarks (which I need). Other than saving all of my current bookmarks / restoring old bookmarks / restoring new bookmarks, is there a way that I can just take the file I need, save it and restore them on another PC instead? All of the tutorials just want to wipe my current bookmarks with the old ones.

If I'm forced to restore old / restore new, does it save all the login data/cookies and so on for my existing bookmarks?
