It's not possible to put items inbetween the new tab button and the tabs, and have button be inside the tab strip (which is taking up all the space in the top toolbar, even if you can't see it). This is technically not really fixable inside Firefox. You can drag tools to the right of the new tab button and the little dropdown icon, when in customize mode, and then this won't happen and the new tab button will stay on the left.
