Hi benlev, I understand that some of the bookmarks are missing when you sync to a new computer. I understand that you have tried to sync now and removing the account a few times. However I do not understand the outer left and outer right files missing when you look at the folder where the files are kept? Are you syncing from a mobile device? It may be in the mobile bookmarks folder. The network issue for Firefox sync was just resolved, were you seeing any error messages: "Unknown error occurred"? Does searching for a missing bookmark in "Show all Bookmarks" show the bookmark after waiting for the initial sync to complete?
