Every time I make add a new bookmark in Chrome now it will constantly make copies of that bookmark, often hundreds of times.
I thought it might be an issue with Chrome sync since I use Chrome between two computers. One of the main reasons I even use Chrome is because of sync. Resetting Sync in Google Dashboard doesn't seem to do much though. After I log back in the problem persists. If I delete all my bookmarks and re-import then from a backup HTML file, Chrome will just start duplicating ALL of my bookmarks.
