Did you use Firefox's built-in Refresh feature? (Refresh Firefox - reset add-ons and settings) It is supposed to migrate your bookmarks automatically.

If that did not happen, try using the Restore feature -- does Firefox find your bookmark backups?

Restore bookmarks from backup or move them to another computer

If that doesn't work, could you check whether your old profile folder (old data) is on your Windows desktop inside a folder named Old Firefox Data?

I did a Refresh Firefox but the bookmark didn't get transfered to the new refreshed firefox.

1- I do have a old firefox folder data with a bookmarkbackup file on my desktop that i didn't see it earlier.

2- Where is that reset add-ons and setting location so i can try if it will migrate those backup or not?

If you follow the steps in the Restore Bookmarks from Backup article, it will lead you to menu that may list dated backups. If not, you can use the Choose File... choice to point Firefox toward your desktop, Old Firefox Data, into the bookmarkbackups folder to use one of those backup files. Does that work?
