We will not lose any of the bookmarks, password stored on upgrading firefox. We will not even lose our browsing session and we can restore all the windows and tabs after the upgrade.

Hello, Thank you for all your replies,I have not yet up graded to FF4 but What I have done just in case is to write down all my Bookmarks I did not have many it also gave me the chance to delete some that were no longer used,

Regards Monty

You can export the bookmarks to an HTML file to have a backup copy.
You can import that copy if you need to restore those bookmarks. Importing an HTML backup will merge those bookmarks with the existing bookmarks, so you won't lose bookmarks that you already have.
