hello. if I update my Firefox browser to version 2, will my bookmarks be kept and my settings and everything??? does it simply replace the older version?
You can use the software MozBackup you can backup and restore bookmarks, mail, contacts, history, extensions, cache from all Mozilla applications: Firefox, Thunderbird, Seamonkey etc.
Just Backup your profile before upgrading (also handy after pc crash etc. )
I think you can import your bookmarks since when you install Firefox it also state if you like to saved your bookmark. And also using MozBackup could really help as well.
