I have used Foxmarks/Xmarks for a long time now. I use it to manage my bookmarks across 5-6 machines. And on occasion log in on say a family members computer to grab a url. The issue with my Chromebook is that it want let me turn off "sync" and I keep getting pop ups telling me to disable sync. Should make the change and let Chrome manage my bookmarks? Can you access your bookmarks from the web as with Xmarks?
