stsalt said

it has same "ROOT WEB ADDRESS"

But is the full address the same? Likely not if it goes to a page. Have you tried to edit the old bookmark?

Copy the link to the current location (address bar), open the bookmark you are using, and replace the current address with the new one.

thanks for reply Fred, but i mentioned " (i know you may select old one with some action to overwrite it)", editing old one is known one, i wish there would be an option to overwrite old bookmark by auto like:

first day http://www.book.com/page=1

next day http://www.book.com/page=2

save all each day to http://www.book.com bookmark (root)

thanks
