You will need to use an extension like Sort Bookmarks to permanently change the bookmark sort order.

i dont get it, before in a older version of firefox i could just drop down the menu on the right and hit show all bookmarks, now i dont have that option no more? why would mozilla take that out?

You can drag the Bookmarks Menu button that shows the bookmarks in a drop-down list and drag the Library button that gives access to recent bookmarks and history from the Customize palette to the Navigation Toolbar. The Bookmarks Menu button has a "View bookmarks sidebar" menu item.

See "How do I add the Bookmarks Menu button to the toolbar?"

Note that the Views menu in the Bookmarks Manager (Library) only shows a sorted view in the Library and doesn't sort the bookmarks permanently.
