I assume Bookmarks Toolbar still appears on the toolbars list, which you can turn "on" using either:

• right-click (on Mac Ctrl+click) a blank spot on the tab bar (or the "+" button)
• (menu bar) View > Toolbars
  On Windows, tap the Alt key to activate the menu bar temporarily.
• in Customize mode > Toolbars button (see: Customize Firefox controls, buttons and toolbars)

Does Firefox show a checkmark for Bookmarks Toolbar there, but it doesn't show in its usual position below the main toolbar?

If the toolbar shows but it's empty, and you can't find the Bookmarks Toolbar Items control anywhere, try the "Restore Defaults" button at the bottom of the Customize tab.

Any improvement?
