Press Ctrl+B or go to View >> Painel >>Bookmarks

• You can toggle the Bookmarks sidebar on/off via "View > Sidebar > Bookmarks" or "Ctrl+B" (Command+B on Mac)
• You can toggle the History sidebar on/off via "View > Sidebar > History" or "Ctrl+H" (Command+H on Mac)

You can find toolbar buttons to open the bookmarks (star) and the history (clock) in the sidebar in the toolbar palette and drag them on a toolbar.
There are two bookmark buttons with a star in the Customize window.
One star button has a drop marker that open a Bookmark menu (you may not see the drop marker in the Customize window).
The other star button without the drop marker opens the bookmarks in the sidebar.

Did you check the View menu?

• Press the F10 key or tap the Alt key to bring up the hidden Menu bar.

Thank you! Hiting the F10 key brought up the hidden menu. Your help is very much appreciated. Peter
