I have the opposite problem - my bookmarks are syncing, and adding many, many copies of them! I have my bookmarks organized in 9 folders and something keeps syncing copies of them over and over. I have over 500 copies of these folders in Safari now and it is dog freaking slow! I started deleting them one at a time, but it was taking about 20 seconds a pop. Checking online I found others with the problem and they suggested deleting the files from the Library folder. I did it, imported a saved copy and things were great...until sometime tonight the same thing happened again! Ugh...
