I guess i did not explain myself well or violated some terms. When i open a blank firefox page, i want to see ans determine and pin icons for sites only i choose with no duplucates but firefox irregularly sometime pins recent visits i do not want on with i call the landing page. Ironically some sites i use a lot do not get pinned, so i have to reveet to less desirable, for me ,bookmarks to control sites i want remembered. As it is end up with multiples and of sits i do not want pinned.
