I tried posting my solution but some of the code I included caused the post to error and it did not save.
You need to use a browser that you do not use for anything else as the customizations apply to all windows for the browser, in my case I used Firefox.
You need to turn off the Title bar. Right click on the toolbar and select Customize Toolbar then uncheck "Title Bar" at the bottom left.
Again right click on the toolbar and select Bookmarks and Toolbar then select Never Show.
That get part way but now you need to use a custom CSS for Firefox to hide all the other top stuff and that is where I had a problem posting what you need. You need to create a userChrome.css file in you profile, Google how to do this, then there is a bunch of CSS you need. I found it by Googling "Hide toolbar with one tab" and "Hide address bar". I can share the code if you have anther way for me to get it to you.
