Add some Toolbars to see the entire height of the persona image = 3000px by 200px (I don't think the full width of the Persona image can be seen on anything except a wide screen TV display).

Firefox comes with 3 Toolbars, the Menu bar, the Navigation bar, and the Bookmarks toolbar. It may vary depending on your operating system and whether you have Large or Small toolbar icons selected, but on my system I need to have 10 toolbars showing to see the full height of the Persona I have selected. YMMV

View > Toolbars - Customize Then hit the Add New Toolbar button, name that new toolbar (I named them Spacer 1 -7), and then add a single Space to each new Toolbar. Repeat until you have 7 more Toolbars. When you're done - hit the Done button.

I have not been back to this topic for a very long time because I have been so very happy with the outcome-beginner's luck I guess but now I also am ready to get a new one but I require one that covers the screen-every bit of it until I open Firefox (currently, it is a field of incredible flowers that are really quite amazing-not my typical choice but in surprise-I made the choice) and then the other choice is for just the upper and lower areas. I had no idea that there would be such a long time until I would change and now I forget how I did it but your suggestions may do it. I know for sure that this is not the way I accomplished my pleasant end but now-whatever works.I've now done research and have favorite, prolific persona maker who shows great talent but this gets no work done, he, he! Thanks for taking some time figuring out what we want so that it is available for those of us who work on such things. Bye, S
