My personal laptop went down so I used my wife's for a road trip. I synced her browser (which had never been synced before) thinking that it would wipe out her bookmarks (that she didn't care about) and replace them with mine, but what it did instead was merge her bookmarks with mine and now all across my 5 synced devices I'm seeing her bookmarks as well as mine. I don't want to see her bookmarks. Is there anyway to revert from this and get my browser(s) back to their previous state before doing this? I'd prefer not to have to manually remove her bookmarks if possible although I know that's an option.
