You can add extra empty toolbars if you want to see more of the persona. You can create new toolbars in View > Toolbars > Customize You have to place something on a toolbar (drag a Space on it) before closing the Customize window as empty toolbars are automatically removed.

that does help. are there any other ways to see more, maybe to make the work area somewhat transparent?

A persona is only displayed as a background image of the toolbar area at the top and not on the website part of the browser. So the only way to see more of a persona is to increase the toolbar area by adding extra toolbars.

i have added toolbars as you suggested, and it has helped a lot. i know there is more to the art of my persona because i can see part of it at the bottom, about 1/4" high. do you know if i can move the search window which is now at the upper right corner of my screen? maybe over to the left and under the address window? right now it covers part of a face that is on my persona. and again, thank you for the help thus far! i do appreciate it.

Both the location bar and search bar have a flex property and will take all available space. So it won't help you if you (re)move the search bar, that will only make the location bar take that space.

You can set a fixed maximum width for both bars with code in userChrome.css in the chrome folder in the Firefox Profile Folder

Add code to userChrome.css below the @namespace line.

@namespace url("http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul"); /* only needed once */

#urlbar-container {max-width:400px!important}
#search-container {max-width:200px!important}

You can also make the location bar and search bar a bit more transparent.

#urlbar {opacity: 0.5!important}
#urlbar:hover {opacity: 0.8!important}
#urlbar[focused="true"] {opacity: 1!important}

#searchbar .searchbar-textbox {opacity: 0.5 !important}
#searchbar .searchbar-textbox:hover {opacity: 0.8!important}
#searchbar .searchbar-textbox[focused="true"] {opacity:1 !important}
