You can move the "Bookmarks Toolbar items" from its current position to the new position while the Customize window is open.

Thanks for the reply, but I don't see the options you're talking about. Here's a screen shot.

Didn't you look in the View menu (View > Toolbars > Customize)?

The "3-bar" Firefox menu button shows in the screenshot at the right end of the Navigation Toolbar

You need to be in customize mode if you want to make changes to the toolbars.
