You can move many of the elements of the User Interface when you're in the toolbar Customize mode.

I don't want any toolbars as they take up valuable screen space.

You can hide all toolbars (View > Toolbars) and open the bookmarks in the sidebar (View > Sidebar) or switch to full screen mode (press F11 to toggle).

Thanks, but it's still involving toolbars, read sidebar. OK, it's not on the screen, but I just wanted to stick it on the left side of the navigation toolbar, maybe in place of, or next to, the 'arrow' (go back) button. Oh well, can't get blood from a rock. {:o)

You should be able to have the Bookmarks Menu button on the Navigation Toolbar, but you will only see that button only if the menu bar is hidden.
You can try to place it on the left end of the menu bar if you want the menu bar to be visible to see if that works.

Oh boy, you lost me here... The Bookmarks Menu button is already on the right side of the Navigation Toolbar. Comes that way from the factory. {:o) I want to place it on the left side of the navigation toolbar instead of the right side. A) It won't 'drag and drop' there and B) there's no room...

If the Customize window is open then you can drag the Bookmarks Menu button to the left end of the Navigation Toolbar or any other position (I have it on the left end of the Tab bar).

That did it, cor-el. I've now got the Bookmarks Menu button where I want it!

Thanks!
