evertytime i changed to another version or another computer i must move the bookmark and saved password manually, is there any program to backup it?

you can use MozBackup from mozbackup.jasnapaka.com it's a simple utility for creating backups of Firefox, Thunderbird, SeaMonkey, Mozilla Suite and Netscape profiles. It allows you to backup and restore bookmarks, mail, contacts, history, extensions, cache, etc.
