XMarks worked great synchronizing 3 computers for almost a year, and then it confused the contents of my profiles. I was able to recover all my bookmarks, but it took a lot of time to sort them out and reorder them.
I tried again, this time with one profile, and two computers. A few months later XMarks lost most of my bookmarks. After recovering about a dozen bookmark backups, and spending a few hours reordering my bookmarks, I uninstalled XMarks.
I am trying Firefox Sync, which is working fine, for the week that I have been running it.
