Customizing Toolbars with Voiceover on Mac OS

Hi folks,

I've been trying to customize my finder's and Safari's toolbar by selecting the customize toolbar option in the view menu. However, I can't seem to find any accessible way doing that as all the items appear as images and not checkboxes or anything. I have tried using drag and drop, using the mouse lock function to rearrange items, and anything else I could think of but couldn't make it work. Any suggestions or insights?
