asterius, sorry can't help with the Sync issues. Just wanted to point out that you can backup passwords as well as bookmarks. ---- One method for backing up passwords is to export them to a csv file. See this article for more information: https://support.mozilla.org/en-US/kb/export-login-data-firefox Although that is perhaps less secure than other methods, as the exported list won't be password protected. ---- Alternatively you could try Firefox's new backup feature, which will allow you to set a password for the saved data. See this article for more information: https://support.mozilla.org/en-US/kb/firefox-backup ---- There is another method for creating a local backup of passwords, although this is more of an advanced technique. This involves finding your local profile folder on the harddrive and, with Firefox closed, backing up the files "key4.db" and "logins.json". If you are using a Primary Password, then this might be preferable to the first "export to csv" method mentioned (as the files will be protected by this password).
