hi, in the firefox quantum default layout the combined library icon for bookmarks/history/downloads...) is replacing your bookmarks button that you're used to - when you go into customization mode, you can place the dedicated bookmarks button back onto the toolbar though ;-)

Customize Firefox controls, buttons and toolbars

Thanks philipp... I found out online after I asked the question. I wonder WHY in the world they did NOT import current bookmarks and set that icon on the toolbar???? I wasted almost an hour looking for the answer.

found it! but it didn't was displayed on the customize menu!
