Last year my computer died so I got a new one. All ran as normal for a few months, then the other day I noticed that all the bookmarks from my old PC had suddenly appeared on my new one, how has that happened? There has never been any kind of connection between them, and they've never been on at the same time. Only similarity is I use Chrome on both machines, and if it is a Chome feature, why did it take around 3 months? Is there a way of deleting them in bulk as I don't need a lot of them anymore.
