I'm having a problem with Sync for about two weeks. Syncs keeps always syncing, but it's not working. I seems to be stuck syncing my bookmarks. I usually sync passwords, history and bookmarks. I tried syncing alone history: no problems, the same with passwords: no problem, but when I do the same with bookmarks, it never ends. I also noticed that, when sync gets stuck (always the blue arrows rotating), firefox history stop working, because visited links does not show as visited, and I have to restart firefox and then all links looks like visited (different color). So, is there any way to check what's going on? Maybe it's just one bookmark with a rare name or someshing, but I don't know how to check it. Is there any log file? I also deleted my account, created it again and problem persists.
